ok so me and boyfriend had sex 4-5 days before my period. we had unprotected sex for like 2 mins before using a condom. He didnt ejaculate. I got my period 3- 5 days later and it was normal. now 4 days after my period (7-8 days after unprotected sex) i have a sore throat and a slight temperature. could this be pregnancy.? or more precisely what are the chances it is pregnancy
