Endometriosis. Me on the my situation.

I was diagnosed with endometriosis after my first miscarriage in 2017. After that, I haven't been able to conceive. I have 2 cysts on right ovary and one on left. I don't suffer from any pain. My periods are normal, no irregular or heavy flow. No spotting. I did all the tests one needs to do before surgery and all of them are normal. My fertility levels, hormone levels etc are all normal. The only deficiency that I have is mildly of Iron and vitamin D. I get myself a scan every 6 months and the size of cysts is more or less constant or it reduces in size. I Couldn't get surgery due to lockdown but I was wondering why I don't have any of the common symptoms associated with endometriosis. Do I still need surgery or can I opt for medication only. Or is there another problem that is invisible. I don't have any other types of cysts or fibroids either. Please enlighten me on the my situation.
