I had sex last Saturday and I haven't been feeling to good, we did it 3 times after that and at one point he thought the condom broke... it didn't though! The condom we used was kept in a box under my school books and clothes. Was the condom defective? I got sick 4-5 times yesterday and I've been feeling nauseous for 2 days. I have really bad anxiety so am I just overreacting or could I be pregnant?
