ok so the other day me and my ex boyfriend had sex and I had missed my birthcontrol pill that day but he didn't finish in side me but I'm pretty sure he was close. And the next day I got my period. And it wasnt supposed to come for a week. And I have felt like puking and have a fatigue eve since. And my boobs were kind of leaking white stuff the other day. And since that day I have taken my birthcontrol. Could I be pregnant??
