Possible Pregnancy Concerns: Delayed Period & Unprotected Sex

Question
I never thought I would be in this situation but need to ask or maybe ease my mind.  My husband and I were trying to have a baby..our second.  My last period was 13Sep08, with my periods being 35-38days long.  My husband and I were pretty active everyday after my pd, pretty much everyday.  There was a day where I remember that I felt like I was ovulating (been tracking for a year but not trying), well I had sex with another on the 10th of Oct.  The condom broke so I took plan b probably about 3-4 hours after intercourse with him.  My first appointment was 1Dec08 and she said I was 9w5d and gave me an EDD 1July09.  Took a at home pregnancy test on 22Oct08 and it was postive.  What are the possiblities of this child being the other mans?

Answer
If you also had sex with your husband around the 10th of October, there is absolutely no way of knowing without a DNA test. However, I would like to note that biology does not necessary determine fatherhood in this case. If your husband is welcoming this child as his, and you wish to stay married to him, I recommend that you don't pursue this further and continue to assume it is your husband's.

Best wishes,
