Ok, so I usually get my period around the 9th of each month, well that has come and gone it is now the 18th. I have had really painful cramping, like I am on my period, but the cramps are even worse. I kept thinking I had my period but I didn't it would just be discharge that had some blood in it, I don't know if that is spotting or not because I am not familiar with that, I am only 17 years old, and yes I have had sex before. Does anyone have any imput?
