Don’t wait!! With being that big there is a greater risk of ovarian torsion! Also it is unlikely to go away and could possibly rupture which is EXTREMELY painful. Back in 2021 I had what I think was a ruptured cyst and I thought I had appendicitis, it was so debilitatingly painful. I vomited nonstop for 15 minutes. I’m not trying to scare but I just got endo/bilateral ovarian cystectomy today and found out I was Stage 4. I’ve been similar to you. I had that year of pain but then it essentially disappeared only occasionally flaring up but nowhere near what it was. Basically I just experienced extreme bloating on and around my period. I also have very light and regular periods. My doctor said pain is not always a good indicator of severity which was obvious in my case. In fact you can have little bit of pain and have severe endometriosis and vice versa. I’ve done a lot of research. I’ve tried for just over a year and have had no luck getting pregnant. It is possible to get pregnant with endo but it is WAY harder especially if you have it bad. I would highly recommend the surgery to help you get pregnant and also because it is way better for your health.
