Hi,
I have stage 4 endometriosis and had excision surgery in September 2021 to remove the cysts. I had egg retrieval immediately after that. My cysts are not back but before FET the doctor said that I might have hydrosalpinx based on my USG report. I had left side pelvic pain during ovulation (where my hydrosalpinx is) but apart from that no other pain. Anyway, my FET was done on the 21st of May and since then I have had constant pain in my lower left abdomen which radiates to my leg, groin, and back. It's been 18 days now. My beta HCG was negative but I am not sure what this pain could be. Could it be due to the excess amount of estrogen used for embryo transfer that could have caused inflammation or flared up endo?
