Hello I've had unprotected sex with my partner and he has ejaculated inside me. However I dont know if it was deep inside or just in. We've had sexual encounter on 18 Oct, my period due are usually by 24th or so, I've not taken 72 hr pills but now I'm getting anxious about the chances. If i take the pills now will it be helpful? Kindly guide me properly as I'm stressed about this in case I'm pregnant . UPDATE - - Black bleed_discharge My periods have come today but it's little amount n black discharge I wanna know when does black or brown discharge occurs..my periods this time are late by 6days, so kindly advise
