I developed some cysts as well, and because of my medical history the doc didn't want that to continue. Like Grog, BC pills were the solution. But instead of a stronger dose, I am on a continuous dose. Most people take an active pill for 21 days, then are off for 7. I don't take a break, just start a new pack right away on day 22. It was a little bit of a hassle to make the insurance company get it. On the upside, no more periods and no more cysts!
