Hey guys, so I had surgery on my ovaries last month and my dr put me on the pill to try and shrink my cyst that are still there. I’m on the last week of my first month and I’m just wondering how long it take you guys to start. I’m on day 2 of the last week and still haven’t started. Didn’t know if that was normal or not
