This morning I woke up with really strong and painful menstrual-type cramping that lasted for about an hour with no bleeding. I just had my period about a week and a half ago. I haven't had sex and I have not been on hormonal birth control for over a year. Are there diseases or conditions that could cause this to happen? I am going to see my gyn. in 2 weeks, so I will ask her about it then, but I just don't want to sit here and panic for the two weeks.
