So I’ve been on birth control for 3 days and my period originally was supposed to start in the next 4days to come. Will my period still come when I’m on the pill or not until I finish all 21 pills Brand: Microgynon 30

It won’t be a period anymore, it will now be classed as breakthrough bleeding, it may come in those days, or the pill might hold off the bleeding till your in your break week

Your natural cycle no longer exists since you’re now on birth control. Irregular bleeding may happen but there is no way to know
