"when i began using birth control, i had severe reactions to every pill that the doctor gave me. of the side effects which are listed on the pamphlet,i had all of them except the most severe ones. i had three periods in 2 months and i was shaking and in a great deal of pain. i am small and to me it felt like a massive overdose. the nuvaring has been a lifesaver. the ring slowly releases the hormones so i don&#039;t feel overwhelmed and saved me from a lot of future worry and stress."
