ok so april 8th was my last regular period. i had unprotected sex 21st 22nd 24th 25th and 27th the 29th i started something. usually my period is heavy and red but now in a couple hours time it only takes up i little spot of the tampon and its pink with some brown spots on it. and when i wiped earlier it was a blood clot but im wonderin of thats coming from wearing a tampon or if that even matters. what i wanna know if its implantation bleeding and if not y did i get my period twice this month?
