Bleeding for 16 months and other symptoms that could be Endometrial Cancer.

[Swyrsrn]

Can someone please give me some advice! I'm sitting here sobbing in pain and I don't know what else to do. I'm 21 and I have a 15 month old disabled daughter. Ive been diagnosed with PCOS since i was 15 after taking the depo shot and rapidly gaining 50 pounds in under 4 months. At 29W2D into my pregnancy I lost my mucus plug, began bleeding, and started leaking amiotic fluid. I have since had a miscarriage 8 weeks ago. I have PCOS but am otherwise healthy. I have been bleeding since I lost my mucus plug with my daughter and she is now 15 months old! I have been having extremely painful bleeding for 16 months straight. I have only stopped a few times for no more than 3 days. I have been in extreme pain. I have been extremely fatigued, dizzy, nauseous, had pelvic pain, watery discharge, frequent urination (negative UTI)...ect. I feel extremely sick all the time and my migraines are nonstop. I don't even know what it's like not to have a headache anymore. Any time I have stopped bleeding for a couple days and have had sex with my husband during that time it is extremely painful and I begin to bleed immediately. I also have cervix pain so bad that it makes me just scream and I feel pressure. I have been to the OB and hospital repeatedly and they have done a vag exam and tested for stds (which I knew I didn't have anyway bc I have only been with my husband for 6 years) and they came back normal. But 3.5 weeks ago they my 2nd transvaginal ultrasound that showed my endometrial lining was still 19.5mm thick and previously was 15.3. I asked if I could have endometriosis too and he said no I do not but that the lining should not 19.5mm thick and have increased from last time so he put me on the pill and said he wants me back in 8 weeks for another ultrasound to see if it has decreased any. Well everything that I have read has pointed to endometrial cancer and I still am bleeding terribly and am in do much pain that I don't know what to do. NO one will help me and I'm just getting worse. The doc said I'm too young for that type of cancer that it doesn't happen until 40+ and that it's just my PCOS probably acting up but he said my cysts are fine and I actually have less and they are smaller so this doesn't make any since. And he said there is nothing he can do to stop the bleeding if the pill doesn't help. Shouldn't he do a biopsy of something regardless of my age because of all of these symptoms and pain I'm going through and that my lining is really thick??? Any advice please
