"i have been on sprintec for almost 6 months now. i am 20 years old and had been on the nuvaring since i was 16 and loved it until i had an injury that required i took the ring out. the first 2 months of the pill i had absolutely no side effects whatsoever. i felt exactly the same as i did on the nuvaring. at 3 months however my breasts have increased an entire cup size and are very sore all of the time. this is the only side effect i am experiencing. i take my pill at 9pm each night. i have not experienced any weight gain."
