"I have been on Gianvi for four months. I&#039;ve been on birth control since I was fourteen (I am now 19) for irregular periods and with Gianvi, I didn&#039;t have any periods. I was okay for the first couple of months, but now, at the fourth month, I have no periods, migraines all day, everyday, spotting instead of a period, sharp cramps during the time when my period was supposed to come, I am unable to wear my contacts now (they hurt SO bad and end up giving me a headache if I force myself to wear them [even with BRAND NEW pairs]. It is pretty effective when it comes to preventing pregnancy because I did miss a few pills, but in the the past, with other brands, I&#039;d miss pills and NEVER have any side effects. Now on NuvaRing."
