I've been taking mononessa for almost 9mo and I started skipping the placebos (28 pack/middle) in early December so I wouldn't have a period . So I hadn't had one since the first week of December. I tried to skip the month of February as well but the pharmacy told me I couldn't pick up my birth control for another 2 days . I try to pick up my new pack that Sunday or hours before on Monday before my scheduled time to take it . Since I missed those 2 days I made up for Monday & Tuesday on Wednesday. Since my period was actually suppose to start that week missing those 2 pills triggered my period anyway and it came that Thursday February 9th. It's March 6th and my period is still on and off.. why is that? It'll go a whole 24 hours without bleeding making me think I am finished then starts back. Could missing those 2 pills in February be the reason my period is on and off for over a month?
