Constant pain in right side pelvic area.

Earlier I used to have pain in right side pelvic area just one day before and on the first two days of period, due to endometriosis. But since my last period on 12 oct, I am having constant pain in right side pelvic area. I also have pain in that area if I am bloated. I was prescribed dienogest for 2 months to reduce endometrial cysts (right ovary & posterior uterus) & 2 months after taking the last pill, I got my periods. Due to the pandemic, I have not gone for tests but I feel that my condition has worsened. I also have fertility issues because of my condition and have been unable to conceive despite medications like clomid, etc. Is this constant pain due to endometriosis? As I want to conceive, should I get surgery done to remove endometrial tissues or try ivf and then get the surgery done? With my condition of endometriosis & adenomyosis, will I ever be able to conceive?
