Can You Get Pregnant During Your Period?

Sperm and Egg

How You Get Pregnant – The Bare Bones Basics

It is surprising how many women do not fully understand the mechanics of getting pregnant. For the majority of women, their menstrual cycles are 28 days long. Menstrual bleeding is only the beginning of the full cycle. The length of your cycle is determined by counting the number of days between the first day of bleeding until the day before you start bleeding again in the next month. In order to get pregnant from unprotected sex, you have to have sex around the time you are ovulating. For women with a 28 day cycle, ovulation usually happens around day 14 or two weeks before your next period starts. The possibility of getting pregnant is present if you have sex during days 11 to 15 of your cycle.

Let’s take a look at what really happens in a woman’s body. In general, an egg is released into the fallopian tubes at ovulation. This happens at about 14 days after a woman’s period starts. The egg will travel to the uterus (or womb), and can be fertilized anywhere along the route. The life of an unfertilized egg in the womb is a short one and in the absence of sperm will begin the process that leads to menstruation.

Having Sex During Your Period Can Result In Pregnancy

While uncommon, it is possible to get pregnant from having sex during your period. Cycle length and how long the menstrual bleeding lasts can play a part in an unexpected pregnancy. It all comes down to a numbers game. Women usually will ovulate about 14 days before their next period starts.

If your cycle is shorter in length than 28 days, there could be an increased chance of getting pregnant from having sex during your period.

For example, let’s say your cycle lasts 25 days instead of 28 days and your period bleeding lasts for 6 days. Sperm is known to survive up to 5 days after ejaculation in the woman’s reproductive system. If ovulation occurs 14 days before your period is due, it would occur on day 11 of your cycle. If you had sex on day 6 of your period bleeding, the sperm could potentially survive until day 11, ovulation day. Having the sperm present and waiting at the time of ovulation could most definitely end up in a pregnancy.

Another time when you could get pregnant from period sex is when you have irregular cycles. When a female is in the early and late years of menstruation, her cycle often varies from month to month as well. Any one of these reasons, combined with unprotected sex, makes it possible for a woman to get pregnant during her period.

    It is not likely but it is possible. If you don’t want to get pregnant, it is best to use some sort of contraceptive method.

    Most likely not unless you have very short cycles.

    Whats considered regular cycle and short cycle

  • Vickie B.

    The average normal cycle length is 28 days – calculated from the day your period starts to the day before it starts the next month.

What Vitamins Should I Take And Avoid? What Foods Do I Avoid? Can I Eat Peanuts?!

  • Vickie B.

    If you had regular periods and your dates are right, you should be starting your second trimester. You really need to go see your doctor NOW and ask all the questions you have.

  • Vickie B.

    A pregnancy based on what you described here wouldn’t show up as a pregnancy just yet.

  • Ness

    I had sex while on my period we didn’t use no protection and be didn’t pull out on time. Can I end up preg?

    It’s remotely possible, but not very likely.

  • tracy

  • soso

    I had sex wth my boyfrnd wthout condom,den nw my timmy z gtting big n ma breast are cuming out yellowish thick milk,n ive gt pains,heart burns am i pregnant

  • Vickie B.

    You need to take a test and see your doctor.

  • Vickie B.

    Unfortunately, if you are only spotting and not having full fledged periods, it would appear that your system is in the process of perimenopause. The chances of getting pregnant in the late part of your 40’s is pretty slim without medical intervention. It’s possible but not likely – sorry :(

  • Vickie B.

    It’s possible, but unless you have very irregular or short cycles, it doesn’t seem like you would be ovulating so soon after your period. Seeing the date of this comment, did you turn out to be pregnant?

  • lauren

    Me and my bf had sex on the same day my period came. Mind you it came early because I took a plan b pill. That only last like 3 days. Could I be pregnant

  • Vickie B.

    I’d think the chances are pretty slim that you would have gotten pregnant at that point.

  • Esther Garcia Dominguez

    My last day of my period of last month was july 29,2014 n I had sex on July 30,2014 but he just pull it out n then put back in but he did it 2 times can I still be pregnant while iam on my period right now ??

  • Vickie B.

    Based on what you are saying, chances are that pregnancy is not very likely based on your timing of having sex.

  • Sarah

    Well I had sex about 3 weeks ago and I got my period the day after is it possible for me to be pregnant??

  • Vickie B.

    No. Ovulation typically happens about 14 days after your period starts. You can only get pregnant from sex around when you will be ovulating.

  • mrs jennings

    Hi me and my husband had sex Friday n sat in today I got my period but my pregnancy test said im not pregnant is it because I took the test Early

  • Vickie B.

    Well, in order to get pregnant you need to have sex when you are ovulating, which is about 14 days before your period comes. Having sex 2 days before your period starts will not lead to pregnancy in most cases.

  • Doria Diana

    My last 2 baby’s are 15 months apart and were indeed conceived on the last day of my period so yes its possible just depends on you

  • nicole112994

    I started my period on October 5th, I had unprotected sex on October 7th, we are trying to conceive.. But my period have been off schedule every month, last month my period was two weeks late, & this month it’s a day early. I’m just curious if it worked & I did conceive when should I talk the test?

  • Vickie B.

    The earliest I would test would be on the 19th or so.

  • nicole112994

    So take a pregnancy test on October 19?

  • Vickie B.

    That would work.

  • Alexandria

    I’ve been on my period for a while now. I just had unprotected sex with my partner on 10/ 9. I don’t feel different but could I be pregnant.

  • Vickie B.

    If you are having a period, then no, you most likely are not pregnant. If that is not what you were asking, please feel free to clarify your question.

  • WorriedWoman

    I had my period, it came on time was a normal flow and everything. The third day of my period (it’s always 5 days) I had sex without a condom but he pulled out and then came like 20 mins after he pulled out.

    I was not worried that I’d be pregnant we do it often.

    I’m still having random dull aches like period pain but not nearly as bad. But not bleeding. My period started on Oct 12th. I was originally worried I had a tampon stuck inside me (even tho I took it out when I had sex). But I can’t find anything in me and my bf tried and couldn’t find anything. I started getting worried I may get TSS if I really do have a tampon in me. But I started reading that the pain could mean I’m pregnant. I really can’t be pregnant at this point in my life. It would be more cruel for the baby because my life isn’t together yet.

    Do you think I could be pregnant? On Friday it will be 14 days after my period started which is what I keep seeing is when most women ovulate.

    Is 5 days a short period? And do you think I could be pregnant?


  • Vickie B.

    You wouldn’t be pregnant from having sex on the 3rd day of your period. The random aches that you are feeling could be to ovulation getting ready to start. Since you are so concerned, it would be best that you make an appointment with your doctor to address your concerns.

  • crazzy

    I had sex with my gf on her 4th day menses many of people’s saying that more chance to get pregnancy….
    What can I do for it I don’t no what to do please help me give any suggestion..

  • Vickie B.

    Actually, if your girlfriend has a typical 28 day cycle, the possibility for pregnancy is there but not likely. In a 28 day cycle women usually ovulate on day 14 so you have to have sex closer to that time.

  • Charlie

    So lets say my period is a heavy flow, and I mean heavy. It usually lasts about 4 days. Would it be okay to have sex while I was on it?

  • Vickie B.

    Yes it should be okay. The likelihood for pregnancy is small but it is possible if you aren’t using protection though.

  • kb

    I just had sex a day before my period and he came in me. Am I likely to get pregnant?

  • kb

    I just had sex a day before my period and he came in me. Am I likely to get pregnant?

  • Vickie B.

    Not likely.

  • mimay

    i had sex with my husband during the first day of my period, and bleeding slows down on the 2nd day.. its been a week now, and I’m having some strange actions, like mood swings, and feels like throwing up (but still I can manage not to) , and fatigue.. Is it possible that I might be pregnant, coz we had an unprotected sex, and he didn’t pull it out. help

  • Scherry Samaroo

    i just start to see my period on December 13th 2014 and i have unprotected sex around 2:30 pm in the afternoon of the same day as i am seeing my period . Can i get pregnant after i see my period for this month ?

  • teen17

  • Worried

    My cycle is short of like 22 days my last day of my period was on Sunday and I had unprotected sex that night and in the morning after. What are my chances of being pregnant having a short cycle

  • Caitlin

    I’m am really worried that I am be pregnant.. Two weeks ago I stayed with my boyfriend for the weekend and we had sex and we wasn’t being real careful, and I was two days from being off my period and now I’ve been eating a lot. But I’m sick at the same time, but I’m not taken a test yet unless I miss my period. Do you think I’m pregnant?

  • Vickie B.

    It’s not likely but it is possible. Taking a pregnancy test in about a week and a half should let you know for sure.

  • Vickie B.

    It’s not likely, but it is possible depending on when you ovulate and how long your cycle is.

  • Vickie B.

    If you are taking your birth control regularly then the chances of getting pregnant are pretty small.

  • Vickie B.

    Actually, your chances are higher than normal because you will ovulate earlier.

  • Vickie B.

    If your period is late, take a test.

  • Scherry Samaroo

    my period start on 13th December and finish on 19th December 21014 . Can i get pregnant next month if i do not see my period for next month

  • Vickie B.

    Do you have a period every month? It almost sounds like you don’t. If you don’t have one very month, it will be hard to say when to have sex to get pregnant.

  • Scherry Samaroo

    yes i does see my period for every month, but this month i have sex on the first day of my period , but can i still get pregnant after i see my period ?

  • Vickie B.

    It’s not very likely.

  • Scherry Samaroo

  • Danielle

    I had sex during my period and we pulled out on time, can I still get pregnant?

  • Vickie B.

    Unfortunately, I can’t answer this question for you. You will have to go and see a doctor about this.

  • Vickie B.

    If you had unprotected sex, then yes, the potential to get pregnant is there.

  • Vickie B.

    Yes, there is a possibility you would be pregnant based on the information you provided.

  • Vickie B.

    It’s possible but not very likely.

  • Samantha

    I had unprotected sex than started my period a few hours later was wondering if i could still end up pregnant or no?

  • Vickie B.

    Probably not.

  • spaceylacey

    I had sex the last three days of my period an sperm got inside of me is it possible that i will be come pregnant ?

  • Vickie B.

    It’s possible but not likely. Any time you have unprotected sex, there is always the possibility that you will get pregnant.

  • peh hong huat

    few day ago i have sex with my gf but today she dosent have period may i know is she gonna be pregnant as today should be have period

  • Vickie B.

    If her period was due to start now, you would not have gotten her pregnant from having sex a few days ago.

  • Ella

    I had my lmp on the 1st of july had sex on the 4th and had sex again that month on the 19th , i have a 34 day cycle and my due date is 7th april. I got conceived on the 19th or possible on the 4th? Im 27 weeks pregnant

  • Vickie B.

    You most likely conceived on the 19th.

  • Annie

    I’m asking a logical question
    A woman,after her bleeding ceased had an unprotected sex a day after her final bleeding , therefore what are the chances of getting pregnant?

  • Vickie B.

    Typically, for a 28 day cycle, ovulation happens around day 14. Sperm can survive up to 5 days after ejaculation. The answer to your question depends on how long the bleeding lasts. Cycle day 1 is the day you start bleeding, so you should be able to figure out the chances of getting pregnant with the info provided here.

  • AnxiousLady

    My last period was on nov. 27…it lasted 6 to 7 days. ..i currently tested positive for pregnacy…i been with my man for a year and we are very happy…the thing is on dec 25 at 2 in the morning i might of cheated due to being drunk…is it possible thats wen i got pregnant?

  • Luciano Romero

    Me and my gf have had sex every week and she has not been able to get pregnant. We even tried her most fertile days 8-18 days since she has a 29 day cycle and we had sex on her period. Could she only get pregnant on her period?? We’ve had sex two almost three full months every week except her period and she hadn’t been able to conceive?

  • Vickie B.

    Well, to be honest, how do you know it’s not your sperm that is the problem? I doubt that sex during the period would up your chances. Ultimately, sometimes pregnancy take a while to happen. If you don’t get pregnant by 6 months (if you both are over 35) or a year if you are younger than that, you should visit a fertility specialist to find out what the issue is. You both can take fertility supplements, like FertilAid, that will give both your systems a tune up to help improve your fertility and increase your chances of getting pregnant.

  • Vickie B.

    It would really depend on how long your cycles are. If you typically have your period every month, about every 28 days, then you would have ovulated ovulated on December 11th. Having sex on the 25th would not have resulted in pregnancy.

  • Luciano Romero

    I see, I never have problems ejaculating or pain ejaculating or during sex at all. And I usually cum a lot, but a huge majority always comes out of her always.

  • Vickie B.

    Unless you get checked out, there is no way to know if your sperm count is at a good level, or if your sperm are moving as they should. The volume of ejaculate isn’t a good indicator of good sperm health.

  • lovelylady56

    I need help. I had a regular period december 4th and spotting on January 2-6 I was confirmed to be pregnant at 3 weeks, when is it most likely that I conceived? I had sex with my boyfriend during the end of December and had sex with my ex the 5th and 6th of January. Help please. Who is most likely the father?

  • lovelylady56

    The doctor said by my blood test I am only 3 weeks.^^

  • recovery

    I have an irregular period. I was supposed to start on the 26th. My period never came. I had sex today on the 31st and the condom broke. Is there still a chance I can get pregnant? Please help me!

  • Vickie B.

    If you have normal 28 day cycles, the sex at the end of December would most likely have been the time you got pregnant.

  • Vickie B.

    If you have irregular cycles then there is no way to really tell if you would get pregnant due to the broken condom. The only way to have a better guess is if you knew for sure if you were ovulating at the time.

  • Marie

    My last period was 1 jan then came again on the 31 jan. I had unprotected sex with my partner on 1 February and we both came at the same time. My period only last for 3 days but now on the 4 – 6 days I had spotting and it is dark brown. I feel cramps these days, feeling very sleepy all day, my saliva taste sour once in a while during the day, and feeling dizzy. Will it means I am pregnant? Pls help me…

  • Vickie B.

    Unfortunately, I can’t offer any opinions on your circumstances. I am not familiar with your condition or the medications you were taking. You really need to talk to your doctor about this issue.

  • Silvia

    I had sex on the 4th day of my period. Is it possible for me to get pregnant ?! And my cycle is normally 28-30 days.

  • Vickie B.

    If you have a 28 day cycle, you will typically ovulate on day 14. Sperm can only survive a max of 5 days after ejaculation. So having sex on the 4th day would have viable sperm only until day 9 of your cycle, way too soon to catch ovulation.

  • worried teem2

    i had unprotected sex with my gf during her 3rd or 4th day period ,it is possible that she get pregnant? im afraid if she get pregnant

  • notsure

    I had my period on feb 14 and it last for 3 or 4 days this particular time it lasted till feb 17 which was my finishing off day and on this day I had unprotected sex but he didn’t come inside of me but he did come a little bit on the outside of my opening and lately it period has been irregular I suppose to be getting my period at the end of the month but lately getting it whenever and feb 20 I started having a little bit of pain and haven’t been feeling like myself at all is it possible that I had conceived.

  • Jenny

    Hi! I was wondering. My bf and I were fooling around but we didnt have sex although we were grinding with no clothes on. That was about a week ago. On that week, i started to feel a pain on my right side that lined up to the level where my belly button is. the pain wasnt lower. but i also felt sore on that side, like its how i slept and my bf has sharp hips that may have dug into my side and i have sensitive skin so that may have been what cause my pain. he also felt pain on his side too. then this weekend, he had sex a few times but used protection and we stopped long before he ever came. the condom didnt break or anything. for about a week i have been feeling like 2% nausated in the back of my throat but i didnt vomit. i feel that way after i eat or when i dont at random times of the day. also i have been burping every now and then but sometimes i feel that way anyways , dont feel well, and have GI tract issues. Anyways, I usually have my period on day 21, 22, or 23 counting after the 6th day of my period. i always have regular periods. Its day 22 currently and my period hasnt come yet. ive been feeling pms symptons just like when im about to get my period. I know if i WAS pregnant, it would have been from precum, but i usually always check my bf to see if he is wet or not. so what are the chances i am pregnant?

  • Amber
