"i was on gianvi for two years and just stopped taking it because side effects were getting to me. pro: cheap, cleared up my ache and prevented pregnancy. for several months it reduced my migraines and i felt no mood changes. con: over time, my migraines got horrible and more frequent, breasts increased a cup size, felt in a constant &#039;brain fog&#039;, had constant breakthrough bleeding that started triggering bacterial vaginosis infections and got vaginal dryness. i think this may work for you if you aren&#039;t sensitive to hormones."
