My LMP was 12/09/17. I had sex with Guy #1 on the 17th, 18th and 19th. I had sex with Guy #2 on Dec 25th. When did I get pregnant?

Answer

Based on your last period, your fertility window may have been between December 19th and December 29th. Being that you were with both guys during this time, I could not give an accurate answer. I suggest speaking with your doctor about a paternity test.
