Feeling frustrated

This is kind of a rant/looking for advice kind of thing. For the pat maybe three years my health, both mental and physical have been up and down. It really start around early 2016 when I had the Skyla IUD our in. My boyfriend (now husband) and I were being careful because we were not ready for kids yet. Well as soon as the Skyla was put in I had horrible cramps, bleeding very heavily, and feeling very sick. My doctor told it would be normal for two or three weeks. So I stuck it out. Two months past and I’m still bleeding heavily every day and now sex was so painful. So I went back in and requested a different doctor. He did and ultra sound and found that my IUD had been placed wrong. Instead of it being up right in a T shape, it was completely sideways and digging into my uterus walls. He asked if I wanted it removed or for him to replace it with a new one. I told him to take it out. After he took it he put me on the pill. I tried 3 different birth control pills and every single one of them made me sick. So I stopped taking them. It was about June of 2016. (Side note, I have always had irregular periods.) After Skyla was removed my periods became very irregular. The pills were not helping to regulate either. So I decided to stop with birth control. I started having really bad pelvic pain and sex was painful too. I went to my doctor who ran tests and said it was just cramps. It wasn’t. This carried on into 2017. My now fiancé and I were in a better place and decided we wanted to start trying for kids. And after several months of trying I went back to my doctor to have my hormones tested because I was only getting a period once very few months. She tested and my hormones came back as normal so she was stumped as to why I wasn’t having a period. Fast forward to September of 2017, I went to the hospital because I was having pelvic pain so bad I was unable to stand. So they scheduled an exploratory Surgery to see what was going on in my uterus. The doc said it looks fine but she said she scraped a lot of scar tissue away and that my ovaries looks like there had been cysts. I asked if that was what was preventing me from getting pregnant and she said no. Fast forward a bit, it has now been almost a year since I last had a period and the pelvic pain has only gotten worse. I am at a total loss. I have been having pregnancy symptoms the past week but I am scared to get my hopes up since I figured there was a little to no chance of me being pregnant without a period. Please if anyone has had similar experiences please let me know. I’ve been struggling with this for a long time and I feel very alone.
