Aftr symptoms and conditions

I used Nuva Ring about a year ago and decided to stop using it due to major mood swings, (Going from laughing to crying in a split second) but I recently decided to try it again, as I liked the conveinence of it and the fact that it's the only birth control I've used that hasn't made me gain weight. Well, I've had the ring in for about 2 weeks now and I'm not liking it!!! I've been feeling extremely fatigued, nauseas, constipated, experiencing heartburn, having brown spotting and abdominal cramping. I don't know if I should keep this thing in or take it out. Right now, I'm feeling sooo nauseas I'm contemplating going to the hospital.

i went to the dr. due to a herniated disc. i received an injection in the bottom. before the nurse took the needle out i statred to feel funny. i thought it was because i was thinking about it too much.but before i could walk all the way to the waiting room i felt nausea and faint. i sat down waiting for my release papers. i stood up asked the recpt. if i could lay down some where. i was trying to breath normal, but was starting to faint. i told her i was going to faint, she went to get the dr. i had then passed out. i believe i had an allergic reaction. i was sweating,cold and clamy. i think i was out for a few moments. woke up on the floor. i did start to sneezing, scratchy throat. i did lay there for a while. they checked by blood pressure from time to time. aftr bout 30 min i was able to leave. had allergy syptoms all night but seem fine now.
