Ok so I've been on birth control for 9 months and I've had sex 3 times in three weeks (using condom) one per week. last night was my last pill before my period week will start. The only problem is the comdom first time we had sex broke like a min or two in but he didn't finish in me we changed condoms right after. But I threw up last night around 1 but it could possible be something I ate .. Any thoughts ?
