"i have been on this shot for almost 3 years now, starting out just to help with abdominal pain and now for use of birth control. i love that i have never had a period let alone spotting, no cramps, nothing. just recently i have been having terrible headaches that make me nauseous. i have gained at least 15 lbs, which is very depressing, and sex drive...well that&#039;s long gone(which seems very odd for a 20 year old). reading the reviews helped a lot, thank you!"
