Of its horrible side effects. The side effect that's making me curl into a ball in horrendous pain is the cramping. ((Note: when i was using the nuvaring the cramps didnt get this bad until the 4th month in.)) The pain is so bad and I've been constantly taking ibuprofen for it and it helps but they keep coming back. I'm on the 4th out of 7 day of this period and the cramps are severe. Is this normal? Do I need to go see a doctor? Can you give me tips on how to ease them?
