I had my period on December 10th. I was with Guy #1 on December 22nd, and Guy #2 on January 1st. 12/22. Who is the father?

Answer

Based on your last period, your fertility window may have been between December 20th and 30th. If you ovulated early in your cycle, it could be Guy #1. If for some reason you ovulated later in your cycle, or not during the estimated fertility window, it could be Guy #2. Unless you know the exact day you ovulated, I cannot make a guess. I suggest speaking with your doctor.
