Hi. So I thought I was pregnant due to outer course with 1 layer of clothing protection (my boyfriend wore underwear) . Anyway, I got my period a day late, but it still came and I was really happy. But now it's Wednesday, my period started last Friday. I'm bleeding brown blood (almost black) and have light brown discharge and occasionally I'm still bleeding red blood .. Which seems odd. This is my 5th day and I could've sworn I was done.. Because my periods only last like 4 days, but I'm still bleeding and having back and stomach cramps! Could I be pregnant?
