So, I recently discovered that I have an ovarian cyst. I got a bunch of info from the doctor and they told me about the different types, like functional cysts and dermoid cysts. The doctor told me that he was pretty sure I have a functional/follicular cyst. However, since I am on birth control, I feel like it should be impossible that I could get that kind of cyst since being in the pill prevents ovulation from occuring. I don't have PCOS or endometriosis, so I can't have any of those kinds of cysts... basically my question is how can you get an ovarian cyst while still being on birth control? I hope this isn't a stupid question but I am genuinely curious.
