My LMP was on December 9th, and it lasted until the 14th. I had sex with guy #1 on December 16th and on December 21st. Then I had sex with guy #2 on December 24th. I took a pregnancy test on January 7th and it came back positive. Who's the father?

Answer

Based on your last period, your fertility window may have been between 12/19 and 12/29. As you were with both men are at the same time, there is no way for me to make an accurate guess as to who the father of your child is.
