We had sex a little over a week ago. We used a condom and everything but it was some weird brand that I don't really trust. I have been off my period for about 3 weeks. I was off when we had intercourse. I should be getting it soon either this week or next but I don't feel any post symptoms of it yet. No mood swings, no cramps, no breakouts. I'm not worried at this point since we did have protected sex but there's always that little chance. And since I'm not on birth control he thinks I should. Should I?
