We were save and all, the condom didn't break, didn't get cum and where close, but after sex I started feeling weird, like pain in my lower stomach, that was at midnight, which means we had sex b/w 10 to 11:30, the next morning I took plan b at around 10, but it 10am the next day and I'm still feeling the same way, do you think I'm paranoid or is there something wrong?
