18 days of bleeding wtf!

Adriana • CNA 🏨 MOM OF 6 BLESSINGS. THANK GOD FOR MY RAINBOW BABY 🌈

I've been bleeding 18 days straight without showing its going to stop. I literally finished a box of 38 tampons. I'm fed up. I feel weak and dizzy. Bleeding very very heavy that my tampons soak thru and I stain my underwear. I don't know what to do at this point. But I do fear the bad news if I go to the ER. I had this happen when I got a d&c and it backfires I was bleeding like a faucet. I almost lost my uterus because of it. I fear this is going to be the issue again. Anyone have some friendly advice?
