So my period was off last month by 9 days, and i hadn’t had sex at all in 5 months. Finally saw my boyfriend the 26th was supposed to start the 24th. Didn’t start until the 3rd. But had unprotected sex the whole time ... and now it’s 27 and again ... no period but I’m super exhausted and my backs been killing me and my boobs have gotten super hard and tender and i squeezed them and I’ve had clear- milky discharge come out of them... could i possibly be pregnant?
