I was a rebellious teen

I’m an adult and married now. My husband and I have been ttc for almost three years. After months of no positive LH tests, I knew it was time to go see someone. I kinda of had it in the back of my mind before we wanted to start a family that there may be something wrong because we had unprotected sex for years and I never got pregnant from the careless act. An ultrasound confirmed that I do not ovulate. I had blood work done. I do not have PCOS or hypothyroidism. Blood work confirmed that I didn’t ovulate as well. Why I don’t ovulate is unknown. I had an HSG test and my tubes are not blocked. I got put on clomid for three rounds in a row, nothing. OBGYN referred me to a fertility specialist. I took letrozole for a few rounds, nothing. Three IUI’s nothing. I have had excruciating periods for years-to the point of puking because the pain is so bad. Pain during sex too. After the failed IUI’s I demanded a hysteroscopy which found 3 polyps in my uterus which were the size of a kidney bean. I Was told this was more than likely the cause of us not being able to conceive and the cause of the pain during periods. My periods weren’t painful for about two months after that. Then back to the painful periods again. 6 months since the hysteroscopy I am still not pregnant. I had one IUI 3 months after the surgery, it failed. My husbands sperm count is always normal. For the past few months I have been getting positive LH tests- still not pregnant. Lately, I have had this painful heavy feeling in my uterus and ovaries. Similar to the feeling of being forcefully weighed down. I started to think about the unprotected sex I had before I met my husband, and remembered that I never got tested for STD’s-I was worried I had pelvic inflammatory disease. So, I got tested a few days ago-every STD you could think of came back negative. Thank God! They tested my urine too for a bacterial infection and it came back negative too. So now, I am left with no answer to this journey. My fertility specialist told me that getting a laparoscopy to see if I have endometriosis is pointless because it can cause scarring and damage. So here I am to wonder. Why am I in pain? What is causing it? Why does my uterus and ovaries feeling this way? Why am i not pregnant when I am healthy and in my 20’s? It is interfering with my life. My desire to have a my own child..a family...is more than you can ever imagine..it is heart wrenching...please do not mention adoption on here..that’s not a thought for me..maybe in the future but not right now..I’m in my 20’s and I am already thinking about having a hysterectomy because of the pain and that alone breaks my heart...is there anyone with knowledge about this issue on here? With a possible answer? Or advice? Or words of wisdom?
