I am pregnant and am 20 weeks and 3 days today. I had sex with guy A before or on July 11th at the latest, took Plan B after the encounter, and started my period on the 14th. After my period ended on the 19th I had sex with guy B multiple times. I took a home pregnancy test on August 9th and was negative, and again on the 21st, which was positive. Whatever the outcome is, my baby will be loved and supported. Just wondering if guy A has a logical potential to be the father?
