Who could be the father?

[Anonymous_Xoxo]

I had a one night stand with a guy on December 14th and he came in me but I pushed it out. I had sex with my boyfriend the next day, and so on so on & he always finish off inside of me. My due date is September 12th and I am now 26 weeks and 5 days. Who could be the father? And another thing, my boyfriend is having morning sickness, toothaches, back pains, and even weight gain does that make him the father?

Incidentally, how long have you been having unprotected sex with your boyfriend? Is this a relatively new relationship or have you had unprotected sex with him for years and not gotten pregnant?

We already have a 3 year old son together so I know that's not the case. We split up for about 6 mos and I was dating someone else and he ejaculated in me every time we had sex but I never got pregnant with him. Me and him split up, &  I got back with my boyfriend and we've been having unprotected sex and I still wasn't able to conceive. That's why I'm confused. I have a one night stand and sexual intercourse with my boyfriend and now I'm pregnant.

And in the very beginning of my pregnancy, I was 5 weeks and a couple of days along but their was no yolk sac found. It had me thinking I conceived late and it would make it my boyfriends child.

I had a one night stand 3 days after my period and sex every other day with my boyfriend up until ovulation and afterwards

I would stick with my original advice, which is to assume the one-night stand has a lesser chance than your boyfriend does, by a whisker. You should ask your doctor about the 7 weeks 5 day versus 7 weeks 3 day conundrum, but it doesn't make any difference from the point of view of needing to do a DNA test to put the question to rest forever. Anytime someone has sex within a week or two of getting pregnant and then does the same with someone else, a DNA test is called for.

Hi, Annie I see on my early ultrasound that the CRL is 7 weeks, 2 days. My Dr went my LMP when he said I was 7 weeks, 5 days but by THE CRL measurements I was 7 weeks, 2 days.

Talk to your doctor about all of your findings and see if you are correct in your interpretation of what the doctor went by. But you really can't rule someone out by a 2-day or 3-day margin. It's too important, affecting all of your lives including that of the child. Because all of these dates are so close together, a DNA test is still something you should plan to do.

If, at your January 29 ultrasound (would you check and see if it was really January 29? That is an assumption I threw out there and you did not confirm it), you were told that you were 7 weeks 5 days GA, that means that your conception would have been about 5 weeks 5 days previous to January 29, or around December 20. Also, when you put the estimated due date given to you by the doctor from the early ultrasound (September 12) into a conception calculator, December 20 is the date suggested by it for estimated conception date. This is just two conclusions from the same data (including the guess that the ultrasound was on January 29) but so far it suggests that the guy on the 14th was just barely too early to have produced the pregnancy. Sperm can live 4-6  days in your body, and it swims fast ("pushing it out" is way, way too late, and millions of sperm come out at one time). So you have a suggestion that the baby was not from the guy because he was too early but only by a hair's breadth.

I would go through the pregnancy assuming the baby is from your boyfriend, but would test with both guys after the baby comes so you will never have to wonder. You need to test with both guys because just getting a negative from the other guy will not really confirm it, you need to get a definite yes for one of them. And you really do not want to be party to deluding your boyfriend into raising a child that is not from him, these things have a way of coming out sooner or later, and the passage of time makes it a lot worse.

Yes. It was Jan. 29th

As I said above, so far it suggests that the guy on the 14th was (just barely) too early to have produced the pregnancy. I'd proceed with that notion, and then do a DNA test when the baby is born with both guys, to put the question to rest forever.

OK, so, you got the ultrasound at 7w5d; was that also when they told you the due date? And was the due date based on the baby's measurements, not on you reporting to them when your last period had come? (Was the ultrasound done around January 29?) Has the estimated due date been changed at all since then?

[Anonymous_Xoxo]

Yes they told me my due date based off the ultrasound sound and I was told at my last appointment that my baby was measuring kind of big for 24 weeks and idk what that means exactly.

[AnnieBrooke]

How early in the pregnancy did you get a due date that was from an ultrasound? Your boyfriend is having something called couvade, which is pretty cool, but I think is more to do with his sympathetic connection to you than any biological evidence that he is the father. If your due date came from a very early ultrasound, you could assume your boyfriend was the dad. But unfortunately, not if your ultrasound was much past the 7th week and not if you didn't get your due date from it.

I got it at 7 weeks 5 days
