I've been on Gianvi for years, started on Yaz but switched to Gianvi and have been on it for probably 5 years. I'm on the fourth placebo pill and still no period... I've had unprotected sex a few times this month with my boyfriend of 3 years. He has good self-control and pulls out always. I usually get it the second or third day (third night at the latest) how worried should I be?
