How Long From Conception Is Implantation?

When you are trying to get pregnant, you are always looking for clues to let you know that your hopes and dreams are on their way to being reality.

One of the initial signs that women look for, as a sign that they are pregnant, is implantation bleeding.

What Happens Before Implantation

Before implantation bleeding is a possibility, there are several steps that need to occur in your body.


On average, your ovaries will release an egg (ovulation), into your fallopian tubes, 14 days before your period is due. Your egg will survive 12 to 24 hours after ovulation, and then will start to disintegrate, making conception impossible.


If your timing for intercourse is good, there may be a lucky sperm waiting to fertilize the egg (conception) upon release. Healthy sperm can survive up to 5 days after ejaculation in the woman’s reproductive tract. Optimally, having sex, as close to ovulation as possible, will increase your chances of conception.


Once conception has occurred, the fertilized egg, will travel down the fallopian tube to the uterus. As the egg is traveling, the cells will continue to divide and grow in size. When the egg arrives at the uterus, it will attach to the uterine wall (implantation) and start to produce the hormone that pregnancy tests detect, hCG (Human Chorionic Gonadotropin). The time required for the egg to travel to the uterus and implant is usually between 7 and 10 days.

When the egg implants, some women experience implantation bleeding. You may notice a small amount of blood when you wipe, after using the bathroom. The amount is much less than when your period starts. When the egg implants in your uterus, it develops a layer of cells, trophoblast, which surrounds the egg. The trophoblast provides nutrients to the growing egg by burrowing into the uterine wall. As it pulls the egg into the endometrium, a small amount of blood can leak into the uterine cavity, causing implantation bleeding. Implantation bleeding does not occur with every woman. You will usually see implantation bleeding 4 to 7 days before your period is due.

  • Q

    Hi Vickie, no luck from what I asked 14 days ago. I didn’t end up prego. However I have another question. My cycle date changed this month. I was 1 day late. So do you think it would be a problem if I began taking Chasteberry/Vitex since it seems my cycle came a day late in order to regulate it? Please advise.

  • Q

    The other strange thing Vickie is that my cycle is normally 2 1/2 days and i’m still lightly spotting today. So that’s not normal for me to go this long. So i’m curious if I should start Chasteberry/Vitex or fertilityblend to regulate my cycle and it could also help me conceive. Please advise. Thank you in advance.

  • Q

    I failed to mention this is the 5th day I am lightly spotting

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

    Vitex, FertiliBlend or FertilAid are all good for helping balance your reproductive system. A day late isn’t really a problem though as many different things can make it shift slightly from time to time: Starting or ending an exercise routine, stress, illness, weight loss or gain.

    Thank you Vickie

    I have 1yr and 7mos baby and miscarriage last June.. I had my periods July and Aug. I was Irregular cycle from the start and a year before I got pregnant from my 1st baby I became regular and a year after my baby I became irregular again until now. I had my Cnd last JUne and. the problem is I am confused what is my status now. My last period start date is Aug 3-11. i had intercourse dated: Aug 17,18 and 22 up to date on unprotected sex and all are inside. I take 5 pregnancy test today Aug 26 and its all negative. but Im having this early signs of pregnancy like swollen feet, tender breast, always vomiting and urinate most of the times. is that mean that Im not pregnant and nothing to worry? my expected period is Sept 4.

  • Mikayla

    You had sex 8 days into your cycle. Sperm can live up to 5 days if the vaginal environment is hospitable (the presence of cervical mucus enables sperm to live.) If you had an early ovulation that cycle – releasing an egg on days 9-13 of the cycle – you could have gotten pregnant.

    The spotting you saw was 7 days after sex. It could be implantation spotting, as that usually occurs 7-14 days after conception.

  • jess

    hello, was looking for some opinions here. I started my period on august 6th. I had unprotected sex on the 14th. within that first week after my breasts were noticeably fuller. I thought maybe I was pregnant. I started bleeding on the 3rd. I just assumed It was my period. but after reading all the information on implantation bleeding, im wondering if maybe that is the case. the bleeding stopped on the 6th, normally my periods last 5 days or more. one site said that implantation bleeding is occurs a few days to week before expected menstruation. just wondering what y’all think. thank you

    My wife and I have been working on our second and about 10 days ago Lacey was supposed to start her period and hasn’t. Every other day as she was excited we took tests and was unsuccessful up until this Monday. We had a faint second line and the OB confirmed that any bit of a second generally means positive. Today 4 days since the test past my wife woke up crying and confused. She had a very ligh pink bleeding and re took a test which came up negitave? Is it possible it’s implantation blood? Or could she not be pregnant and starting her period 10 days late? Or worst yet this early seeing we are ver new to this could it be a miscarriage? :( my wife was in tears this morning and breaking my heart any advice would be great!! Please note it was light blood and my wife had implantation blood the first pregnancy. Thanks in advance.. Tony

    I am sorry you are having such an emotional time. Ultimately, only your doctor will be able to tell if your wife is pregnant. Multiple blood tests to see the progression of the hcg would be in order. From personal experience, I had the same thing happen to me. I was very late and it took forever for the pregnancy test to show up positive and, once it did, the doctor confirmed the pregnancy. Unfortunately, shortly after that, my period started. :(

    If your wife has regular cycles that don’t vary very much, it is unlikely that it would be implantation bleeding. Implantation bleeding typically happens about 6 to 12 days after ovulation, which would be a couple days before the period was due.

    I hope everything turns out okay for you!

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

    Lots of things can disrupt your cycle. Based on the dates that you provided, it would appear you just had a shorter bleeding time for this cycle. Did you take a pregnancy test?

  • Faye123

    I finished my period 9/3 and had intercourse the 9,11,13 how likely am I to become pregnant? We are trying and hope this is the only month we have to try. My periods are regular 28 days and 3 days long. Can you please help?!?!?

  • Faye123

    So me and husband had sex on 9-9,9-11,9-13,9-15 and by a couple of calendars I looked up I was fertile and on the 14th I was ovulating. Well about 5 days later my back is killing me my boobs are fuller and hurt and I have this pain in my abdomen and I’m really fatigued and bloated. I’m just wondering how likely am I that I am pregnant or is it in my head? My cycles are 28 days long and periods 3 days. Advice please??

  • Shannon

    My husband and I are trying to have another baby. I’ve been tracking my period for the last few months (07/09/13, 08/03/13, 08/31/13) and according to the WebMD my period is about 27 days. I then downloaded an app called my days that tracks my period and ovulation. According to the My Day’s app and WebMD I ovulated on 09/09-09/14. My husband and I had intercourse on 09/05 (the day my period ended), 09/08, 09/10, and 09/13. On September 9th I started to feel nauseated and had headaches, abdominal pain, bloated, and have felt that way everyday sense. My nipples have been hurting for the last week, I’m more fatigued then I usually am, and feeling full after barley eating anything. Then today I noticed that my stomach is growling and I’m hungry earlier in the am. I know it’s too early to tell, but could I be pregnant?

    Thank you.

    i want to ask a question?

    My last period was on the 27/08/2013 and it lasted for like about 5 days
    & me and my husband have been baby dancing since 6/09/2013 & i THINK i ovulated on the 13/09/2013 & today is the 19/09/2013 & i had my boobs hurting for the past few days like near my under arms part…. and today i have a really bad back pain with leg pains also, i do feel sick BUT not that bad like i can handle it, i have had sleepless nights , & next period am due is on the 1/10/2013

    Can i be pregnant??

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

    Your timing was good so pregnancy is a possibility. Y should be able to test on Tuesday or Wednesday with a sensitive pregnancy test you may be able to see positive results. If you don’t though, you can assume that you aren’t pregnant until you actually get your period again.

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

    It’s possible. You should be able to test next Thursday or Friday to see if you get a positive pregnancy test. Good Luck :)

  • rita

    I had My period on 08/23/13 I took an ovulation test and it was positive on 09/04/2013. I has intercourse the day before, on and the two days after my lh surge. I took a pregnancy test on the on 9/21/2013 and it came back negative :( I have irregular periods. my next period due is 10/14/2013. Did I test to early? I thought two weeks would be enough time to get a positive test?

  • new

    I had my period starting on 9/13, lasted for 5 days and my boyfriend and I had unprotected sex 3 times. The 22nd, 23rd, 24th of those days were the start of my fertile days. I ovulated on 9/27. Now today I’ve had a really bad headache, and some very very mild cramps, just feel strange today. Could I be starting implantation?

  • kimmy

    Hi Ms. Vicki
    I began my cycle on 9/15 (lasted for 5 days)…..we did a home insemination on 10/3 & I obligated on 10/5………today 10/12 I am 7 dpo and have been experiencing nausea, bloating, gassiness (TMI), and dizziness. I also have a dull cramping daily. Could these be good signs?

  • Kmarie

    Hi ms. Vickie,
    my lmp was 9/15/13(lasted 5 days). we did a home insemination on 10/3/13……my ovulation took place on 10/5 or 10/6. Since then i have been bloated, gassy (sorry tmi), tired all the time, and i have dull cramping almost daily. As well as nausea accompanied by dizziness. I am very very hungry in the morning and it seems like I dont get full even when I eat alot. Today 10/12/13 is 7 dpo for me. When should I test and are these promising signs?

  • Dawn

    I came off birth control in May. I’ve always had normal cycles even after coming off the pill. The only change was instead of 28 day cycles, I’m now about a 30-31 day cycle. Last period was Sept 8th-13th. We did the dance on 22nd, 23rd, and 24th estimating ovulation to be around the 24th. My next period wasn’t projected to be until Oct 8th, but eager for news, I took 2 very early tests. One on Oct 3rd and the other on October 5th. Both were negative, but were done before my expected period. I started spotting in the evening of Oct 7th and thought surely this was a sign of my period coming on. But Oct 8th came around and no period. Just a darkish brown spotting. The next 2 days (Oct 9th and 10th) was even less spotting! What? This is weird! It was only a little spotting when using the restroom and the color had changed to a light pink. So, confused, I took another test in the afternoon on Oct 10th (2 days after my expected period) and it was again negative. Yesterday, Oct 11th, was still just the more of the same… very light spotting only when using the restroom. And it seems every day it has been even lighter than the day before. I usually have a pretty moderate to heavy flow and I’ve certainly never missed a period before! Besides pregnancy, what other reasonable explanations are there? Could I actually be pregnant even though I tested 2 days after my expected period and it was negative? If I am pregnant, what is the bleeding from? Isn’t it too late for implantation bleeding? I have so many questions. Oh, it would be so nice to have a clear yes or no answer, you know, a positive test or an actual period. Lol. But sometimes nature likes to keep us guessing :)

  • Kspecial

    Hello my LMP was on 11/4/2013 and it showed that my fertile days are from 11/10-11/15 my fiancé and I had sex the 8,9,twice on the 10th and the 11th it shows my ovulation day for today 11/13 but I’ve been having mild cramps since yesterday 11/12 and today 11/13 is there a possibility this could be pregnancy?

  • Kspecial

    Oh and my cycle is only 23 days

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

    If it says ovulation was supposed to occur today, the cramping you were having was probably mittelschmerz, also known as ovulation pain.

  • Kspecial

    Hello, the start of my last period was on nov.4, 2013 which lasted 4 days and my cycle period is 23 days I did an ovulation calculater online and it said my fertile days are nov.10-15 me and my spouse had sexual intercourse on the 8,9 multiple times on the 10, and the 11. It shows my ovulation day is today the 13th I started having mild cramps yesterday on the 12th is there a possibility this is implantation cramps?

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

    The cramps were most likely ovulation cramps and not implantation related.

  • Brandy

    Hi. My last period was on November 1st. My cycle is about 26 days long. I ovulated between the 9th and the 12th. We have been trying to get pregnant, and had intercourse literally almost every day before, during, and even after ovulation. For the past week, I have been having MAJOR soreness in my breasts. Constant, aching, pain. In the past few days, they have begun itching, and I am not exaggerating, but they are bigger. I took a preg test this A.M. and it was negative. I am due for my period on the 27th or so I think. I also have had no PMS symptoms like cramps or anything…. Am I really not pregnant, or was it possibly too early to test? Thanks!

  • Miranda

    Hi Vicki
    My last period started on the 8th of november 2013 and my cycle is 31 days. I did the ovulation calculator online and it said my most fertile days start from the 23rd to the 27th of November. I had unprotected sex on the 23rd and 24th of November with myn husband and today im am feeling bloated, crampy and have a slight headache. Is it to early to be implantation or is it just my imagination?

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

    Typically implantation happens between 6 and 12 days so it would seem to be a bit early for that. Good luck though! Perhaps your body “just knows” :)

  • kristi

  • christy

    was that for me or for someone else?

  • insight please?

    I had unprotected sex last week on Wednesday. I took my birth control like normal on Thursday, but I forgot to take it Friday and Saturday and didn’t realize it until Sunday. I take Lutera and the missed pills were in the first “active” week of my pack of pills. Now I am having some brownish pinkish discharge with mild cramps ( not intense like menstrual cramps but more of a tightness feeling). I was wondering if I am having this most likely because I missed those pills or if there is a possible chance that I may be pregnant. and If there is the possibility that I am pregnant should I stop taking the BC until I find out for sure if I am or not. I don’t want the baby to be hurt by taking BC if I am and I don’t know what to do

  • jillybean

    My boyfriend and I had unprotected sex 3 times on 11/30 and from the internet my ovulation time is 12/2 or 12/3 is it likely I could have still got pregnant? I really feel that I may have ovulated early bc of what I read about symptoms of ovulation. Please help me. Internet say I can take a pregnancy test 12/12 but I would like heads up if that was possible I could of become pregnant.

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

    Unfortunately, I don’t know. You should talk to your doctor about it to see what they say. I do know if you miss pills, it could throw your hormones off, causing the types of symptoms you are having.

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

    Yes, pregnancy is possible. Sperm can survive up to 5 days after ejaculation so it could have still be alive and swimming when you ovulated.

  • Myra

    HI did you get pregnant though, cos im feeling what you are feeling right now, but my boyfriend didnt ejaculate in me, so am i just having imaginations cos lately, my body feels different and i feel vomittish after eating,
    my stomach feels bloated and tight, please help me cause im kinda of panicking for no reason.

  • leah

    Okay I had my period on Dec.19 2013 and stopped on 23rd my husband and I had intercourse the 26th and the 27th we did not use anything and he came both times in me so is there a chance I could get pregnant not sure when I ovulate and when I don’t its only been eight days since that has happen is it to early to take a test and if I did what would happen thanks.

  • lily2141333

    If you have spotting the day after unprotected sex, can you be pregnant?

  • Kvin

    If my partner didn’t actually ejaculate, and there was sperm in his pre-cum, would that last 5 days? I did the ovulation calculator and my periods have never been on a 28 day cycle. More like between 30 to 35 days. I did the math. I may have been ovulating. I spotted today, but so far there isn’t the usual heavy flow of my period. I never spot either. If the sperm survived for 4-5 days, it adds up. I’m a little freaked. Can I take a pregnancy test in the next couple of days?

  • Erika

    Hi Vickie!
    Here it goes… First day of my lmp was December 23rd. I had unprotected sex with my boyfriend on January 1st with ejaculation. The calendar I keep has my ovulation beginning on the 2nd but my cycles vary every month from 28-30 days so I don’t trust it that much. Plus from what I have been reading you explain that the sperm can survive for up to 5 days! I experienced a weird pinkish/brown discharge the last two days which is not common for me, that I’m starting to believe could have been implantation bleeding because that would have put me at 12 days after conception. I’m not expected to start my period until the 21st. Please let me know what you think my chances are of pregnancy. Thanks!

  • Cookiechris
