During the month of February, I had sex with 2 different guys. One was my boyfriend and the other was my ex lover. We had unprotected sex but, my boyfriend busted inside of me on the 17th, 19th, 20, 21st and 22nd my ex lover took it out before he busted on the 18th. My last menstrual period was February 22. After my ex lover found out I was pregnant, he decided to bust inside of me in March when I was one month pregnant. My ex lover is Trinidadian ( African American ) and my boyfriend is Asian, can you tell a babies skin color during ultrasound? Could this possible be my boyfriend baby? Or my ex lover?
