Hi my names hollie I'm 21 and I've just recently found out I'm pregnant I'm between 5 and 7 weeks I think. Thursday night me and my boyfriend had sex and straight after I had some brown blood on the tissue when I wiped then that was it, then yesterday I bled rather heavily for a few hours and its stopped now have I had a miscarriage the blood was red in the heavy stage, had no severe pain or cramping just felt a little period pains. Has this happened to anyone else?
