I hope to get some answers, since I can't get ahold of my doctor today. On the 27th of Oct. I had sex and had a mistake happen so I got plan B on the next day the 28th. About a week later on Nov. 3rd I got my period (or what I think was my period) it only last for three days and I didnt have any cramps like usual. Then again I had unprotected sex on the 6th of Nov. and took plan B on the 8th. It is now the 13th and I just got my period AGAIN! What is going on??
