Ok ladies. I have a doc appt to get back on birth control for the 1st time since having my son. I was on nuvaring loved it!!! But thinking of getting something a little more long term. Maybe something that will make it so I didn't have a period at all (one thing I loved about nivaring) I get cramps for the 1st two days that are stupid painful like hard to walk and make my knees hip and back hurt like I was hit with a bat. Any suggestions?
