-bc-
pill with only progesteron in it or an other type of progesteron-like
pill) to shrink
the cysts I had. It worked!
After some days they started shrinking and after 10 days they were gone.
I'm on combined bc-pills now (the regular one, like Marvelon/Belara with both progesteron and oestrogen in it) to prevent new cysts from occuring. I know it works, because when I take a break week, after a long cycle of 12 weeks, the damn things grow back like crazy!
