"i was on ortho tri for 4 years but was starting to have some breakthrough bleeding issues with it so my doctor put me on yaz. i&#039;m a broke graduate student so i went on gianvi instead. i keep seeing all these negative reviews on here about it, but i love gianvi. my acne has almost gone away and my cramps have lessened. i did, however, have some issues adjusting to a 4 day period instead of a week long one, but after a few months that straightened out. i love gianvi and have been on it for 6 months without issue."
