Is My Conception Date Accurate Help!!! I Need Info On Accuracy Of Conception Date?

Help!!! i need info on accuracy of conception date? - is my conception date accurate

I had sex with this girl that I saw the week of 15 January. 2006 (possibly 01/16/06), but I do not believe that out. Sperm come, but it could be a possibility. The father never called into question because I thought some of them, May and then to say so far that was the moment of conception (as noted by the physician) in January 07.2006. I know for a fact that does not sleep with her that day not because I was away.How this possible? It is possible that I am not the father and she is right? Date of birth is 10/10/2006, which is not on the day of the performance commencing 01/07/06. Now I remember, she said, hoping that the baby arrives before I think she knows that this is not my baby. My question is .. is possible that the baby belongs to me? are the exact dates of conception? Then the moment of conception from 01/07/2006 will point out that I am not the father?
