I have been on Vestura Birth control for about a year, i take my pill at the same time everyday up until about 2 weeks ago my pill got switched to Gianvi and about a week into it i experianced cramps and pink/brown discharge for 7 days straight! I have never experianced anything like this before and my periods are always regular. Also i sexually active and had sex about 3 days before the bleeding started and now that the bleeding is done my vagina area kind of itches and has an odor.
