What Are The Chances Of Becoming Pregnant When You Have Sex on the Day you Ovulate?




Defining Ovulation

Ovulation is the process by which a mature, single egg is released from a follicle that had developed in the ovary. The luteal phase determines the time of ovulation within your menstrual cycle, generally lasting approximately 12 to 16 days.

The process of ovulation is something that occurs rather regularly, typically happening around day 14 of a normal 28-day menstrual cycle. A short window of 12 to 48 hours marks the time in which an egg can be fertilized after being released from the ovary. During this time, you are most fertile and therefore, the likelihood of becoming pregnant is much higher.

Why is Ovulation the Best Time to Try to Get Pregnant?

Typically, the most fertile time of the month will begin four to five days before ovulation and ends anywhere from 24 to 48 hours after ovulation has occurred. These numbers are figured from the fact that sperm are able to survive within the body for four to five days and eggs can live for 24 to 48 hours following their release. Because the egg’s lifespan is short-lived, it is imperative to attempt conception during this time.

If you choose to have intercourse directly before or on the day on which ovulation begins, it is important to note that the sperm can live within your reproductive system. This means that sperm will still be available after ovulation, putting them in direct contact with the egg. As you might suspect, this greatly enhances your chances of becoming pregnant.




Having intercourse extremely close to the time of ovulation means that you will greatly enhance your chances of becoming pregnant. In fertile couples that experience regular cycles, there is a 25 percent chance of becoming pregnant during each period. This means that 75 to 85 percent of women will become pregnant within one year if they are having intercourse without using protection, such as birth control. Of course, this makes knowing your fertile days even more important. Additionally, taking note of cyclic hormonal and physical changes that occur regularly with your menstrual cycle is imperative as this too can help increase your chances of becoming pregnant.

How do I Know When I’m Going to Ovulate?

Ovulation comes with many physical signs, giving you a good idea as to when it will occur. Some physical signs that you might experience include:

  • Increased Amounts of Vaginal Discharge
  • Breast Tenderness
  • Discomfort in the Lower Abdomen – There are approximately 20 percent of women who will experience discomfort or pain in the lower abdomen while the egg is leaving the ovary. This condition is known as “mittelschmerz” at can last anywhere from a few minutes to several hours.
  • Changes in Cervical Mucus – Before ovulation, cervical mucus is generally cloudy and thick in nature. However, right before ovulation, it will become clear, slippery, and stretchy in a state that resembles raw egg whites.
  • Basal Body Temperature Shifts – Right after ovulation, your body temperature can increase anywhere from 0.4 to 1.0 degrees Fahrenheit.

    What happens if you have sex one day before ovulation?

  • http://www.babyhopes.com/ Vickie B.

    You might get pregnant.

  • mimi

    anyone here?

  • http://www.babyhopes.com/ Vickie B.

    Yes.

  • alex

    What are the chances you’ll still have next period if you conceive during ovulation

  • http://www.babyhopes.com/ Vickie B.

    You wouldn’t really be having a period if you were pregnant. It would be considered early pregnancy bleeding. If you are pregnant and are experiencing any bleeding, you should see your doctor.

  • Stacy

    I had sex on my first fertile day. What are my chances of becoming pregnant

  • http://www.babyhopes.com/ Vickie B.

    It depends. No way to really tell if you were successful in getting pregnant though until you test at the end of the month, around the time your period is due.

  • Mel

    If we had sex again after he cummed on his hand what are the chance of me getting pregnant it was a day before ovulating

  • Tammy

    Im 2days past ovulation and experiencing pain on one side. And I have cloudy white discharge. My boyfriend and I had sex before and during ovulation.

  • http://www.babyhopes.com/ Vickie B.

    It’s possible, but not very likely.

  • http://www.babyhopes.com/ Vickie B.

    How do you know you ovulated? The pain you are feeling could actually be ovulation pain.

  • Tammy

    It’s been four days and I still feel the pain slightly. Im not sure im hoping.

  • http://www.babyhopes.com/ Vickie B.

    Well, if the pain is lingering like that you might want to visit your doctor to make sure everything is okay. Ovulation pain doesn’t typically last that long.

    Hello iam over weigh how to get pargnet

  • yamilex

    if I had sex on February 12 and I used a calculator website that said I ovulated yesterday, but I have a period calendar that says I ovulate tomorrow which is February 17 , my last priod was on the 3rd of February is there a chance that I could be pregnant?

  • http://www.babyhopes.com/ Vickie B.

    You have a small of getting pregnant from sex on the 12th. Healthy sperm can survive up to 5 days (maximum) after ejaculation in your reproductive system. Your chances of getting pregnant are higher the closer to ovulation you have sex.

  • tbaby1896

    I had a period on January 30th and it last for 3 or 4 day On February 5th i had sex n on the 13th on ovulation day can i be pregnant?

  • http://www.babyhopes.com/ Vickie B.

    Not likely if you ovulated on the 13th. Sperm can only survive up to 5 days max in our system. It would have died by the time you ovulated.

  • Breezy

    Okay I had cum injected into me on my ovulation day, what’s the chance I’ll get pregnant?

  • http://www.babyhopes.com/ Vickie B.

    The possibility is there as you had sex when you were ovulating.

  • Mary

    This whole article is inaccurate. The birth CONTROL method I used before my daughter was completely based on you’re infertile AFTER you ovulate and you are most fertile the few days before ovulation and you should start being careful about sex at the end of your monthly period until after you ovulate. I know it works because I used it for years successfully before we decided to try for my daughter. And by using the same method to purposely have sex before I ovulated we were able to conceive the very first time we tried. You are not able to get pregnant at any time. You only have a short window every month and you NEED to have sex in the 3 days before ovulation for maximum possibility of conception. Afterwards is too late. Where do they even get this ridiculous information?

  • danielle

    According to my calendar I have I am supposed to be ovulating tomorrow I had sex last night and my boyfriend ejacualated inside me. What are my chances that I will be pregnant?

  • shayla

    Is it mostly for me to get pregnant the day before ovulation

  • chiluv

    I saw my period on the 23rd of Feb and I had sex on 7th of march and on the 8th suppose be my ovulation time, pls what are the chances of getting pregnant?

  • Ddawg

    What about if you had sex several times unprotected during your most fertile time (and it was confirmed ovulation). And it was within 12 weeks postpartum? Higher than average chance?

  • http://www.babyhopes.com/ Vickie B.

    You timed it right so the possibility of pregnancy is there.

  • http://www.babyhopes.com/ Vickie B.

    I was looking for research on this matter, but there is a lot of second hand information about you being more fertile after giving birth. If you are sure you ovulated, had sex around ovulation and aren’t breastfeeding, there is definitely a possibility.

  • adam

    i had sex after 9 days of ovulation. so what are the odds of conceiving?

  • http://www.babyhopes.com/ Vickie B.

    Pretty unlikely.

  • Naj

  • toya

    What happened if I had sex the 2nd day of ovulation but during sex my discharge was real thick is that a bad sign. I personally feel like the guy I was with has a low sperm count because he has no kids am I likely to get pregnant I’m confused

  • Sarah

    My cycle is every 26 days, my last cycle was on April 10th and lasted until April 15th. I started using my ovulation kit on April 16th and received a faint postive line up until April 19th. On April 20th I received a postive line. We had sex from April 17-19, he ejectulated each day inside me. What are the chances that I could be pregnant? Can you ovulate without seeing the cervical mucus? Confused, please help

  • http://www.babyhopes.com/ Vickie B.

    You can conceive with no fertile cervical mucus but it is more difficult. The sperm use the cervical mucus to travel in your system. You might need to use a fertility friendly lubricant like Pre-Seed to help. You timed it correctly so the chance of pregnancy is there.

  • Rae

    What is the probability of me being pregnant? I had unprotected sex 3.5 days before I ovulated. I ovulated yesterday and I’m still having cramps. I’m 25 years old and never been pregnant or on birth control.

  • http://www.babyhopes.com/ Vickie B.

    It’s possible as sperm can survive up to 5 days after ejaculation.

  • Jamie

    I came on my period April 26 I been having sex as much as every other day since I came off (May 2nd) my period cycle last month was 28 days but sometimes it be late I had sex on the 2nd 3rd 4th 8th 9th 10th and the 11th wat are the chances of me being pregnant

  • http://www.babyhopes.com/ Vickie B.

    You might want to bookmark our ovulation calendar so you can figure it out on your own http://www.babyhopes.com/ovulation-calendar.html

    Based on the data you listed, this is the results:

    Sunday 26th April 2015 – First day of your cycle
    Wednesday 6th May 2015 – A little bit fertile
    Thursday 7th May 2015 – Fertile
    Friday 8th May 2015 – VERY fertile
    Saturday 9th May 2015 – Time to ovulate
    Tuesday 19th May 2015 – A home pregnancy test may work now.

    Based on that info, it looks like you timed sex well for getting pregnant. :)

  • http://www.babyhopes.com/ Vickie B.

    Well, it is hard to say if you weren’t sure when you were ovulating. If you were ovulating and you had unprotected sex, the chance for getting pregnant is there.

  • Ana Martinez

    I had a mc on 31st of March got my period on 29th of April I ovulated from 8-13 dtd 3 days in a row… Now I feel cramps and I’m dizzy can I be pregnant this soon??

  • http://www.babyhopes.com/ Vickie B.

    Well, you would have gotten pregnant as soon as conception happened at ovulation if you are pregnant. You won’t be able to test until at least the 25th though.

  • KMA

    Hi, i came on my period on 5th May and came off on the 8th May, my cycle is currently 28 days and I had sex on the 16th & 17th May – according to my chart this was right in the middle of my Ovulation period. Can you advise if there is a possibility of me being pregnant?
    My partner works away and I only see him at the weekend so this does limit our time for having sex in my Ovulation period unfortunately. I’ve never tried for a baby before and any advice is very welcome. Thank you

  • Marcia Jean Turner

    I had sexual intercourse 5 times the night I started my period.what are the chances of getting pregnant

  • Marcia Jean Turner

    But I also have severe endometriosis

  • http://www.babyhopes.com/ Vickie B.

    If you have a period about every 28 days, then the chances of you getting pregnant at the start of your period is pretty slim. Women usually ovulate around 14 days before your period arrives.

  • Marcia Jean Turner

    No period every 28 days sometimes they are 15 days apart and other times they come every 21 to 23 days

  • http://www.babyhopes.com/ Vickie B.

    Well, it is impossible to say what the chances of pregnancy are with the varied cycle lengths. Normally, ovulation happens 14 days before your period starts, but when you have a cycle length of 15 days, I don’t know when you would have been ovulating.

  • Silver

    So I had sex the 30th and found out today is when I ovulate. What are my chances of getting pregnant?

  • http://www.babyhopes.com/ Vickie B.

    It’s possible, but the percentage has been getting smaller as very healthy sperm can survive UP TO 5 days after ejaculation. So conceivably there could be sperm there to meet the egg when you ovulate.

  • Karen

    I had sex 9 days after my ovulation.
    Is it possible to get pregnant?

  • Silver

    I have occasional stomach pains some worse than others idk if this is a sign or me just being paranoid

  • Tatum Peters

    Okay, I had unprotected sex on the 30th of May. I have been off of birth control for over two months. He ejaculated in me three times he told me. What are the chances of me being pregnant?

  • http://www.babyhopes.com/ Vickie B.

    If you are sure your ovulated 9 days ago by using ovulation tests, then the chances of you getting pregnant are pretty small at 9dpo.

  • http://www.babyhopes.com/ Vickie B.

    It is impossible to say what the chances are. It really depends on when you would be ovulating. If that happened around the time of ovulation then the chances of pregnancy are there.

  • Nae

    I had unprotected sex the day of ovulation, there was no ejaculation inside of me and no prior ejaculation before intercourse. What are the chances of pregnancy?

  • Tatum Peters

    I took two ovulation test the day after sex and they both came back positive. I also had very clear and slippery cm the day we had sex.

  • http://www.babyhopes.com/ Vickie B.

    Without ejaculation, the chances of pregnancy are pretty small.

  • Azael

    I had sex 4 days after my period and then the next day, is my chances of getting pregnant high?

  • http://www.babyhopes.com/ Vickie B.

    It’s possible depending on how long your cycle is. Wait until 2 or 3 days before your period is due to take a pregnancy test. You should get accurate results at that point.

  • Vicc
