Introvale experience?

Hi all,

I’ve been on the Mili BC pill since I was 14. I’m 19 now. I just got prescribed Introvale, since my periods are still heavy and long. I don’t see many people sharing their experiences with Introvale, so I’m a bit nervous.

Is it common for there to be bleeding before the placebo week? And does the risk of break-through bleeding diminish as time goes on? Are there any noticeable changes to your body while on Introvale? Are periods lighter and shorter when they do happen?
