Plz Help!

I'll try to make it short. I got off the implant dec.1 took a plan b dec.14 and came on what I thought to be a period dec24 or the 25 which ended on the 30th.i had sex with guy #1 on the 2nd but he says it's impossible, Sex with guy #2(ex) on the 3rd and he always come inside me dont know if he did that night. He also made comments he couldn't have kids because of his past with other girls kids not being his. and guy #3 (ex) on the 11th which has 4 kids all in the month of January. I really want it to be guy #2 but I have no idea because for a long time for self esteem reasons from family I thought I couldn't get pregnant. As of today I am 27 weeks going on 28 beginning Monday but the baby is measuring a week ahead. I had a 8 week ultrasound and she told me the due date was Oct. 6 & went to another Dr. She told me Oct 1st. Had a 12 week scan and it said the AUA 11W6days but underneath said GA(LMP)12W2days. So I'm guessing there sticking with oct1 still. I was cramping really bad a couple days before I tested and got a positive test January 29. PLZ HELP I AM COMPLETELY STRESSED OUT!! Who's the father?

Getting back to the main issue.

You had sex on the following schedule. It was all unprotected.

Guy 1 January 2

Guy 2 January 3

Guy 3 January 11

If you go with the 8 weeks 2 days / 8 weeks 4 days counts from the first ultrasounds (which is the best you have to go by, later ultrasounds do not matter because babies diverge in their growth rates from the average after a while), that gives a suggested conception date of January 13 with a margin for error of +/- 3 days either direction due to the ultrasound being in your eighth week. Sperm can live 4-6 days in your body. This collection of data gives the possibility that the last guy, the one on January 11, is the dad, rules out the first guy, and pretty much does not suggest the second guy either.

But if you use the due date given to you by the second doctor (which is a puzzle because if the ultrasound really said 8 weeks 4 days, that's not the correct due date), but if you do use it, then the second guy is a little more in the realm of possibility.

You didn't say whether the baby was a boy or a girl. If the baby is a boy, it would be moderately indicative of the second guy not being the dad.

Thanks for responding it's very much appreciated. At the 20 week scan I found out that I am expecting a baby girl. Guy#2 said that it was going to be girl and when I told him he pretty much was right he dissapeared at the fact of being an possibility. Guy#3 that has kids all boys by 3 different women and his last was a little girl by the fourth. So I'm really not sure.
Which is more accurate the AUA or GA(LMP)?
Does it matter if it make it more of a difference if you *** with one guy or the other? Not to be nasty but I've heard this question being asked before.
In the 11th and 12th week, no due date will be as accurate as you need it to be. If from an ultrasound (AUA) there is a +/- 7 day margin for error by then, because embryos can develop faster or slower than normal over time. And trying to use your LMP and count forward is always iffy because not every woman ovulates exactly x days from her prior period. So, neither AUA nor GA from LMP will help you because the one was too late in your pregnancy to give you helpful info and the other was iffy all along.

It doesn't make more of a difference if you have sex more often with one guy or the other, since it only takes one sperm and guys shoot millions in one ejaculation.

The baby being a girl doesn't help you to rule anyone in as much as a boy would have helped you to rule the earlier guy out.  If the second guy has fled, you're probably going to have to talk to a lawyer if you want him to do a DNA test when the baby comes, and find a way to subpoena him.
In the previous response were you saying if it was a boy that it rule out Guy #2 but because it's a girl is a possibility for Guy #2 and Guy#3.
Is it possible to concieve in what was thought to be a period since I took a plan b and the side affects of it is bleeding?
I've seen you make other answers on other woman posts with these types of questions as far as gender ruling more of the other and you've seem to have been pretty right thus far. So that's kind of why I wanted to mention that yes the baby is a girl.
I don't think that with the info you have and the two doctors giving you conflicting due dates that I can come in and say when you conceived. If the second doc was only two days after the first doc and said 8w4d when the first doc said 8w2d, they should also have agreed on the due date being the 6th, but apparently from what you say, they didn't. So none of this is really going to be something that can be figured out from what you have reported.

The fact that the baby is a girl does not rule out the second guy, but it does not rule him in either, and mostly his chances seem less to be the dad because he was a ways from the 13th. But that is if you think the 13th was conception date.

No, you didn't conceive during your period.

I think you should work on getting a DNA test done with guy 2 and guy 3. That's about all you can do.

Thank you very much!! Your definitely appreciated and it's a sure thing. I'll post the results ( just in case it helps anyone else) & just think about baby from here on out.

So your first ultrasound was on the 26th and said 8 weeks 2 days, and your second ultrasound was on the 8th and said 8 weeks 4 days? (If so, they should both have said the same due date. I'm surprised they didn't.)

If your original doctor was correct in saying your due date was October 6, the conception calculator gives January 13 for conception.

How fast after that was the other doctor appointment (where they told you the due date was October 1)? If it was, for example, the next day after the first appointment and what she said was based on an ultrasound, then you have a difficult difference of opinion to sort out. But if the second appointment was weeks later than the first one, and/or if you didn't have an ultrasound at the second one, it is less surprising that the estimated conception date would be different. Some babies grow faster than the average and some grow slower. Because of this divergence, woman are often told a different due date at a later point in pregnancy.  But a fast-growing baby does not change when conception was, and the earliest ultrasounds are the most accurate for trying to guess when conception was.

You also said you had a 12-week scan (that said such and such) "so I guess they are sticking with October 1." But you don't mention when the 12-week scan was (on the calendar, not in weeks) so I can't offer an opinion about whether they are sticking to October 1 or not.

The doctor that stuck with Oct 1 ultrasound was tooken 2 days after on 2/28/18 measuring at 8W4 days. The 12 week dating scan was tooken on 3/21/18, AUA said 11W6 days and the GA(lpm) was 12W2 days. The Dr. That did the scan said they were sticking with the Oct 1 date that was given from the ob of the second ultrasound on 2/28/18.
Which cunfuses me because I don't know if the AUA is more accurate then the lmp. My very first ultrasound was done 02/26/18 measuring 8W2 days, done by a different Dr.

If it helps any, I had a positive home pregnancy test on 1/29/18 and went to the hospital either that night or the day after because of the pains and I tested positive through urine but they couldn't see the baby and kept me overnight to watch my hcg levels and rule out an etopic pregnancy.  Being that this is my first that was by far the scariest, worsest experience thus far.
All of my appointments measure me on time with the October 1 due date. I even heard there are ways to know through what the gender is who it would be. I'm just not sure. I do know I'm 27 weeks and will 28 weeks on 7/9/18. Thing is the Dr never mention days and weeks, she just tell me the week I'm in.
Even more confusing; the ultrasound tooken on 2/26 says the baby measures from crown to rump at 1.83cm.
The ultrasound tooken on 2/28 says from crown to rump at 2.03cm. when looking at chart measurements on line the second US would put at about 9 weeks not 8W4days
2.3cm is nine weeks, not 2.03cm, so I don't think you are going to get anywhere with that.

It is interesting that two ultrasounds, one on the 26th and one on the 28th, said respectively 8 weeks 2 days and 8 weeks 4 days. This is what you would expect them to do; they are saying the same thing. What you would not expect is for them to give different due dates. Some clinics don't use a 266-day count for the time period of pregnancy from gestation to full term (or a 280-day count from last period to full term) but it is still surprising to find this disagreement.
