me and my bf had sex before my ovulation day and on the day of ovulation. both days he came inside me . i took a contraceptive pill about 30 minutes later. 9 days after ovulation, a week before my period was scheduled to start i saw spotting. for 2 days i was spotting really mild cramping etc. i assumed it was implantation bleeding then for the next 6 days ive been bleeding still. not heavy like my regular period but enough to wear it was on my thin pad. ive been cramping throughout . my boobs have gotten larger and extremely sore. should i see a doctor or is everything okay ?
