Does anyone else have this pain?

My dr told me I need an endometrial ablation due to a thick uterus lining. That's all he said, I don't know how thick it is or anything. I cannot afford to have it done yet, so I'm on birth control pills to help manage bleeding. It's not really working, I still spot n bleed. I have also been getting really bad pains lately. It's my lower left hip towards back and shoots around to the front where my ovaries are. And the pain is dull but it gets worse. And it sometimes brings tears to my eyes. I also seem to be having hormone problems. Changes in certain areas like getting more pimples when its that time of month. Does anyone know what's up in that area, or have the same problem? I don't know if this is normal or if I should see the dr again. I cannot afford to go unless I need it. I'm not one who runs to the dr for every little thing. Please, and info or comments are appreciated.
