Hi. I had sex with guy number one around my fertile days. About 2 weeks later I got my period, I don’t know if it was implantation bleeding, it lasted about 6 days, I don’t remember the flow or color. After my bleeding, I had sex with guy number 2 all month and tested positive when I missed my next period. Is guy number 2 the dad? My due date lined up with my last bleeding perfectly at an 8 week ultrasound. But doctors changed my due date by 5 days at 15-16 weeks. I’m horrified for this baby to be the first guys.
