So I last had sex June 28th and my period was on July 6. I haven’t had sex since then. It have fooled around some with my boyfriend. I started birth control at the end of May and am still unsure about my period. It’s supposed to start this coming Thursday but I’m getting really nervous because my forehead has broke out more then usual and yesterday I had cramps worse then any that I’ve had before. I took a pregnancy test this morning (6 days until AF) and it was negative. Should I be freaking out like I am? I’ve heard it only takes one sperm to fertilize an egg but it should be practically impossible that I’m pregnant. I just can’t explain my symptoms other then my pms sysmptoms have changed with my birth control. Is that normal??
