Unbearable Menstrual Bleeding and Pain

I hate having to go through a period. I always lose so much blood, and I might as well be spinning the wheel on how long it will last. I'm currently on week three, and it just keeps getting heavier and heavier. I've been taking iron pills every morning, so hopefully I'm not anemic. I want to call my doctor but I'm scared that one of two things will happen. 1) They tell me to wait it out or they can't see me for a few weeks and I have to wait anyway. 2) They tell me to go to the emergency room. I probably have endometriosis, but I can't afford to get the laparoscopic surgery to confirm it yet. The pain is bad, and otc pain killers don't even touch it. Does anyone have any advice for managing the pain or stopping/lessening the bleeding?

I'm going to vent a little because this is so obnoxious at this point I'm bleeding for a week at a time with a few days off, then it begins again. I know I'm at a high risk of this because of my PCOS, but it still sucks. I'm bleeding through my clothes and sheets, and I'm going to have to spend my very limited income to buy reusable incontinence pads for my bed so I don't stain everything I went through 10 nighttime pads in less than 3 days, and am having to constantly restock. I'm miserable because I'm constantly bleeding and bloated and STARVING. When I'm not on my cycle, I don't eat all that much, but lately I'm eating all the time, because if I don't, I'm in pain from the gnawing sensation of hunger I'm just done with this, but this has been my reality for two months now, and it shows no signs of stopping
