When I was super young. I had cyst on my ovaries and they put me on BCP. I think my mom begged them to though.

They told me it was to shrink my cyst, which could be, but then I ended up staying on it till I got married.
BCP stops the hormone that makes cyst or follies grow. Then it will have good change of going away instead of continuing to grow.
Good luck.
