OKAY girls , my period is 16 days late today, it's been irregular for the past couple of months , about 5 days ago I had unprotected sex but he didn't finish inside me , half way and he wore a condom. I've been so gassy and bloated ! I have horrible cramps and my legs feel weird when I walk , still no period and I'm very constipated , don't want to get a pregnancy test yet because I'd rather save myself the anxiety, should I wait until my period ? Am I overreacting ? What do you think ?
