So I took a Plan B 3 weeks ago 12 hrs after sex and then 5 days later I bled pretty heavy for like 4-5 days, the 30th to the 3rd/4th (pretty much a period) and my next scheduled period was supposed to start on the 16th and I am 3 days late but on the 15th I had this really really really dark brown discharge come out but that was it (tmi sorry but it completely stained the inside of my underwear). I have experienced a good amount of vaginal twinges this whole week, some nipple tenderness last week, discharge, pimples and other familiar pms stuff. This is my second time taking Plan B....the first time I didn’t experience this all that much. Is this normal?? Will my period come?? I’m super nervous...
