Today I have been having SEVERE cramps. No contractions. I labored for 17 hours unmedicated with my daughter and today these cramps are right up there with contractions. Like make me freeze I can hardly breath almost drop me to my knees type pain. I just put a new Nuvaring in today and all of the sudden these contraction like cramps started. This is month three on them and I've never had this pain. I've also been nauseous off and on today. Has anyone ever heard of the Nuvaring causing nausea and pain this bad? I'm almost at the point where I'm about to go to the hospital. I've been having them all day. And no there's no chance I'm pregnant and miscarrying.
