So you would say it would be the man I had actual intercourse with? I know pregnancy from fingering is highly unlikely and I have read that it has to be like dripping off your fingers to potentially cause pregnancy and he wiped his hands off thoroughly so there was no visible semen!
Had another ultrasound today and shows I'm 20 weeks and 2 days! And DOC was 1/22... Ultrasound tech said could go as early as 15th but that's pushing it!
OK. First off, getting pregnant from ejaculate on the fingers is not the easiest way to get pregnant, though it is theoretically possible. If I were *trying* to get pregnant, it is about the last method I would employ short of not having sex at all. That does not mean that in human medical history it has not happened, but it is a less likely way to get pregnant.
But even more to the point, you had two early sonograms. They both suggest conception was around the time period from January 20 - 22. If the scans had not been early in the pregnancy, they would not be reliable, but they were nice and early, and they tend to back each other up, the first one saying January 20 was your conception date and the second one saying January 22.
You said "I think" the event with the guy you are trying to rule out was in early January. Is there any possibility you could be mistaken and it was more like the second week of January? If there is no chance it was that late, had you gotten pregnant from that early January event, the baby would have looked a lot different in scans in February and March than it did. This means the guy from early January is ruled out. Unless, of course, you figure out he was really later than you thought. His chances are still slimmer than someone who released inside you, but if he was right in there dates-wise, you couldn't rule him out for sure. But it sounds like he's out.
What is your due date, October 13 or 15? That also backs up conception around January 20-22.
Hi, you are giving some numbers without saying where you got them. For example, you said "I apparently ovulated on 1/22." Who told you that, did you just calculate it out yourself? If so, you might be starting with assumptions that are incorrect. For example, when a doctor tells you that your pregnancy is in its 20th week, did you know he or she is *not* telling you that you got pregnant 20 weeks ago?
So let's figure this out and check your work. When (calendar date, like, February 22 or March 5 or January 13) was the sonogram from which you learned that you were 5 weeks 5 days gestational age? Did the ultrasound tech tell you that you were at 5 weeks 5 days or did you do the computation? (Because 5w5d it is just a tiny bit late to see only a sac.) If the ultrasound tech told you by looking at the ultrasound and not influenced by other information that you were 5 weeks 5 days gestational age, that would have been counted from a computed first day of last period based on how big the baby looked, not from the presumed date of conception. So, again, what was the date of the "5w5d" ultrasound scan?
