Bleeding none stop

Okay so I I'm 26 and I have polycystic ovaries and have knew since I was around 13. My periods used to be all over the show literally having one every 4-6 months most of the time but I would have the odd few months where they would be regular every so often. I have 3 children 9, 6 and 10 months. I got pregnant with my eldest when I was 16 after loosing a lot of weight then had my middle child at 20. After my 2nd child I had something called cervical ectopy where I would bleed in between periods so had to have coloscopy treatment where they froze the end of my womb. After that the bleeding in between stopped. I broke up with my children's dad Lost weight then gained loads and my periods were all over the show again. I went on metformin in 2018 and got pregnant with my youngest after one month of taking it. After having him I breastfed for a few months so didn't have a period until about 2 months after I stopped but since then I am constantly on my period I will have 2 weeks break from it at the very most but usually its days before I'm bleeding again. I have had a smear and everything came back clear and I've had a scan and everything was normal on that they just said that I've got lots of cysts on my ovaries but I am still fertile. So I've had blood tests done and am awaiting results on them the doctors just want to check my hormone level and I also requested them do a full blood count. Excuse the absolute essay I'm just trying to get as much information that's necessary in this post for use to understand. So basically I am just wondering if anybody else has experienced anything like this because I am really concerned to why I am constantly bleeding its scary because its not normal at all and I have gone from one extreme to another. I constantly have belly ache and I am on painkillers a lot of the time to help me deal with the pain that comes with this. The doctors have also just prescribed me the combined pill I have not been on any other contraception for years because I wanted to let my body try and regulate itself. Please anybody with any insight comment. I feel like I'm not getting the answers I need from professionals and they can't explain it to me either because personally I don't think they have a clue what's wrong with me. Which is why I have turned to glow. To see if anyone on here has gone or is going through what I am. Thanks so much for reading if you got to this point I really appreciate it. Xxx
