im confused, i had unprotected sex about 23rd of july and spotted a little about 9 days after [implantation bleed maybe?] and now my period is due i think as im having really bad cramps that i dont normally get and am only spotting not enough for a pad or anything, this is so unlike me as im normaly quite heavy. im 18 and dont think im too young and would never abort, i dont particularly want a baby as ive just applied to uni etc but i know its not the end of the world, id have the support from family [i think] and my boyfriend im just confused and want to know. did anyone else get this cramping? please help and advise... thankyou
