Please help-miscarriage?

I think I’m having a miscarriage. I just found out I was pregnant with two pregnancy tests and I went to sav a life and they estimated me around 5 weeks but they won’t give me an ultrasound until you’re about 8 weeks. Anyway, I’m bleeding really bad and huge clots are coming out of me, it’s extremely painful. Do I need to let this happen naturally since I’m not far along? What should I do? I’m confused and I think I’m in shock because I was so excited. I don’t want to go to the hospital because from what I understand, they won’t really do anything for me and i don’t want the bill if i don’t need to go. Please give me some advice.
