This month VS last month

So I have cysts in my ovaries and when I first discovered them it was because my cramps were god awful. I was prescribed something and it’s worked wonders for years after. But last month my cramps were next level. I had never EVER experienced that type of pain. It hurt so bad I thought my appendix burst. I went to the er and was prescribed a new medication for my cramps which works very well. But I’m worried that the cysts are getting worse and it may harm my fertility.
