so two weeks i had unprotaceted sex mon through friday. I also took the plan b pill those five days. I know i dont need to be using it like birth control and i know i should get on birth control. but after those to weeks i went and bought hpt. they all came back negative. before i took the pills i was cramping like i was about to to start my period. well i didnt. so today i took another hpt and it came back negative. I started to spot monday but it stopped and tonight im spotting but the blood is very slim when i do spot. could this be a sign that i am fixing to start my period? or should i just not worry about this months period?? Im very scared! could me taking to many pills delay my period for a while?
