Ok so yesterday i had just the tiniest stain of blood in my panties and i thought i was going to have my period but nothing happened after that and now i'm having dark brown discharge in clots, just so you know i can have my period missing for months because i have light PCOS on one ovary and suspected problems with my thyroid. Everything i read on the internet says i'm pregnant and i'm really worried because a week ago i had 'unprotected sex' (he didn't come, didn't even have time to)
