My LMP was on November 28th. I had sex on November 3rd with guy #1, and then on December 4th, I had sex with guy #2. My period was due on December 27th. When did I get pregnant?
If you were only with guy number #1 before your November period, then he is least likely the father. Guy #2 is most likely the father.
