So, my period starts tomorrow or the next day.. So very shortly. I have had protected sex 3 weeks ago, the condom broke, but he didn't ejaculate. We haven't had intercourse since. I have been noticing "down there" that it's been swollen on the inside, almost like it's tightening. No itching, or burning. Just normal pre menstural discharge. No odor. I am wondering if the tightening of the inside walls is normal before periods. I have been reading online and some said it could be pregnancy, but I dont find that likely. Others said that its normal for before periods, but I wasn't quite sure. I need some answers! Thanks!!
