I am a 21 year old mtther of 2 and I had my period on Jan. 11th 2012, on the 15th me and my husband had a mishap (the condom defaulted/broke) the next morning we got the Plan b pill and today January 27th i woke up my sheets were coverd in blood and im still bleeding, my stomach and back hurts. I do not know what this is because i am regular when it comes to having my period. Is this normal and what do i do?
