Can someone actually READ my whole question??!!!!!!!!!!!!!!!!!! URGH?

I have read your whole question (all five times that you've asked it) and have looked at your question history, so now I think I understand your situation. You had sex with two guys, the first one didn't 'finish' but may have left precum in your body, and the second guy did finish when you had sex a few days/weeks later. The difference in your due date could mean the difference in who the father of your child is.

This is unfortunate; however, since the days are so close together it could be either guy. Conception is not an exact science, and even if your period is regular you may not ovulate on the same exact day every month. The ejaculate can live in your system for a few days, and so even if everyone agrees that you conceived on the 7th or you conceived on the 11th of September or even later, there is really no way to ease your mind and let you know for sure unless you get a DNA test.

This can be done prenatally, but is more commonly done after the baby is born. Sorry you're in this situation, and best of luck to you with whatever ends up happening.

I read your whole question. However, figuring those things out has never been my strong point. I'm just wondering why it's so important to you to know specifically which DAY you got pregnant. I would tend to go with LMP over ultrasound....I have long cycles and according to lmp and long cycles my kids actual birth dates would have been a lot more accurate than the early ultrasound suggested....both kids were at least a week past their due dates, almost two weeks

I'm not sure about having bleeding like that and getting pregnant the day after - I don't see why it WOULDN'T be possible.

I'm not sure where people think you would have gotten pregnant on the 7th though. That is a miscalculation. If your lmp was 8/28/08 - you would then count about 14 days for when you were most fertile. That would be the 11th or so of Sept.

I had one of those crazy heavy periods for 5 weeks and got pregnant right after it stopped.

And according to the pregnancy calculator I used, you should have conceived on 09/22/08 based on your due date. Or conceived on 09/11/08 based on your LMP (but yes, that moves your due date up a bit). So based on all that information I'd say you conceived sometime between 09/11/08 and 09/22/08.

it could simply be a case of you ovulated later than normal that month for whatever reason. My cycle was anywhere between 28-35 days (never less, never later) so when I fell pregnant I knew I could be a week out on my dates which was confirmed on my first ultrasound. My second ultrasound was out by 5 days, and I have another scan tomorrow...however at a doctors appointment on Friday I was measuring way bigger than I should have been.

Unfortunately EDD's are not an exact science.

Based on your due date, you would have gotten pg on Sept 22 (you count back 38 weeks from your due date).

Based on your LMP, your due date would be June 4, but becasue of that wacky bleeding, you probably ovulated later, thus the later conception and the later due date...make sense?

So, when did you BD? That would help narrow it down, but based on your bleeding and your due date, I would guess Sept 22, or thereabouts, if you BD'd then or a few days earlier.

In my opinion, it depends on your cycle. and when you ovulate My cycle is 34 days. I am due June 19th and according to my calculations I got pregnant on September 27th. My last period was September 8. If you ovavulate exactly 14 days after your lmp, which you may not, then your conception date would be September 10th (14 days after your last period)

According to the Mayo Clinic complete book of pregnancy that I have sitting right in front of my face, if your due date is the 14th of June your last period should have been around september 7th, your conception date would have been around sept. 21st.

based on your last period that you're giving us, the book says your due date is June 4th.

I think you're about 1 month off because I was impregnated on 8/28/08 and my due date is May 12. I know the exact date of conception because it was only one of three days that month I had sex. I believe your date of conception is more like early or mid September.

your pregnant like a month maybe ?
