I had unprotected sex on August 6 and 7th using the pull out method 3 times total. My period was due on August 21st. On August 16th I wiped and saw a pea size blood clot(sorry if tmi) and nothing else. The next day August 17th I went to the bathroom and it was pink on the toilet paper. That same night it turned to brown discharge. The next day August 18th till yesterday August 21st I had a lot of blood clots on pad & dropping in toilet. Sizes ranged in sizes from pea size to half a dollar coin. So I started my period 5 days early. So could I be pregnant? Or posibly miscarry? This was not a normal period at all! I go tomorrow to see my ob gyn! Just been stressed!
