"i recently switched from yasmin to gianvi by accident (i thought i was on yaz instead of yasmin and asked my doctor for the wrong pill). after reading reviews of gianvi, i was really scared to start taking it. many reviews mentioned increased acne, weight gain, mood swings and heavy periods. i have been taking gianvi for 4 months now and have had no negative side effects. i have no acne, i lost 5 pounds, my periods last only 3 days and are very light and i have had no problems with my mood. i actually feel better than i did on yasmin. each pill works differently for each person and there are people with positive experiences with gianvi."
