"nuvaring is the only birth control i&#039;ve ever used (other than condoms) and so far i like it. it&#039;s a simple process to put it in and take it out and i love that i don&#039;t have to stress about it every day. i used to have unpredictable periods so i love knowing when it&#039;s coming every month. negatives. i have experienced some serious pms symptoms since i&#039;ve been on the ring (not every time but i think it&#039;s getting more frequent) like irritability and general emotionalness, some pretty severe cramps (which i rarely got before), and tiredness. recently, i had a super heavy flow during my period plus cramps. i&#039;ve been getting some headaches and back pain too but i&#039;m not sure it&#039;s because of the ring. i&#039;ve been on nuvaring for about 6 months now."
