Took the morning after pill now experiencing pre menstrual bleeding? Last sunday me and my boyfriend had protected sex, but when he pulled out it looked like either me or him had came, so he thought it might have squelched out of the side and we just wanted to be safe, so on the monday i went and got the morning after pill. It was levonelle (in case thats useful) and i did experience some side affects straight after taking it: abdominal pains, nausea, fatigue, light headedness. Everything was great the rest of the week, then six days after i woke and i was bleeding. I've read that this could mean it hasnt worked, is this true? Thanks for all your help! Also, will it be like regular bleeding like a normal period or just spotting
