birth control
"I have just finished my first month on Nuva Ring. I am unable to take regular birth control because of high blood pressure, and so far no problems from Nuva Ring. Also, I have migraines regularly and didn't want to try a IUD or anything inserted in my arm.  The only problem I have had is when the Nuva Ring is out after the 3 weeks, I get VERY heavy menstrual flow and bad cramps. This is unusual for me, since I usually have a 2 day period with light flow. Don't know if it has anything to do with the Nuva Ring or with having a baby 8 months ago. "
