About a month ago I had unprotected sex with my boyfriend, I panicked and two minutes into it I asked him to stop, within 1 hour of that I took planb (as I said I panicked). Later we started having regular protected sex (condom never broke or leaked). I had this with him two or three times before my period started, and when it did start it was very normal. We had protected sex during my period as well. I had my normal mild cramping and headaches. About 5 days into my (usually 8 day) period I threw up all of the sudden. Nothing brought it on. Then my period slowed down and seemed to have stopped within my normal time frame but when I check again the morning after my stop date and even after that up until now I am still having period type symptoms. Now (10-11 days into my period) I am not having anything reach my panties it would seem like my period is over, but fluid or I don't know if you would call it discharge is still in that light red to brown color as if I am still on my period. I understand that plan be can mess with your period but I am still concerned. This is only the second man I have had intercourse with and he is clean (he’s in the army and I asked him for his annual health screening results from about a month ago) I have always been clean. I am not too worried about pregnancy but it still looms. Please what do you think is up?

Sorry if this is nasty but I am confused and can't find any info...

I don't think you're pregnant... but you should probably call your doctor if you have concerns.

Is PlanB the "morning after" pill?

Yes it is

Were you able to get it over the counter or did you take it under a doctor's supervision?

I would definitely call my doctor if I were you... at least just to get checked out and discuss what you can expect after taking it.
