Okay, so Tuesday night i threw up my birth control pill probably fifteen/twenty minutes after taking it. I didn't take another because I couldn't keep anything down really. The next day i took my pill at regular time and same with Thursday. Then on Friday morning, my boyfriend and i had sex. He didn't finish inside me whatsoever but I'm still a little worried. Could I be pregnant? (I'm on ortho tri cyclen and I haven't missed or taken any pills late this month or last month).
