Paternity

[HLS70]

A woman I was with is pregnant. I had protected sex with her on Januray 4th or 5th. A condom which did not break, slip off, or appear to be damaged in anyway upon inspection (before insertion and after withdrawal). I withdrew immedialty upon if not during ejaculation into the condom. While the sex I had was protected during penetration it is possible that bare penis rubbed against vulva prior to penetration and that pre-ejaculate might have been deposited there. I suppose it's possible that the pre-ejacualate found it's way into her or that somehow sperm leaked out of the base of the condom. What are the chances? I think both those scenarios are unlikely.

She had unprotected (withdrawal method with her intoxicated ex-boyfriend) sex on December 31st. Due date is expected to be 9/18/08 (she was 14 weeks pregnant on 3/20 or 3/21), so the baby is either his or mine and given the scenario probably his. While I understand it's possible that the baby is mine, I believe it is unliklely given the scenario described above. We must wait until the baby arrives, ~6 months, to prove paternity for certain. I'm driving myself crazy with worry in the meantime. Don't know how I can last 6 months of this.

I simply don't know the probabilites. I would very much appreciate a physician's opinion (hopeful that it will give me peace of mind) on how much I should worry. Is this a 1 in 100, 1 in 5, 1 in 1,000 scenario that it's mine?  Just found all this out and I'm scared (obviously).  

PS, not that it's relevant because it clearly didn't work, but she was on the pill.

Hello,

If what you say is true regarding use of a condom (properly, I'll assume) then you have nothing to worry about.

Best regards,

I have a pregnanct calc. and according to it if her due date is 9/18 then her concieve date is Dec. 25th. So i guess whoever she had sex with closer to then. Hope this helps.
