Hello everyone, two weeks ago i had protected sex while ovulating, he did not come and the next day i took a 72 hour emergency pill. However, it is the third time i have taken this pill in less than a year. I noticed that it was doing harm to my body so i stopped having sex in general. Today i was due for my period, but instead i had something that looked like old brown blood. But otherwise, i have had cramps and tender breasts. My old blood only lasted a day and i am hoping to get my period. Am i pregnant or did my cycle get messed up?
