My ex had two sexual partners 16 days apart and then turns up pregnant. I am wondering begat my chances are to be the father. The last day we were sexually together was August 18th. We broke up on the 25th of August. I am not sure how soon they got together sexually but I know it was after the 25th. She says her due date is any were from June 18th to the 25th. What are my chances? I know both male sexual partners didn't were a condom.

I'm going to take a chance and say you are out since August to June is 10 months.
