Miscarriage question

I was given the option to let my pregnancy pass on it's own, and I had started bleeding mid April not a lot though, then about April 22nd I started finally having severe bleeding and heavy clotting, and just the last few days my bleeding seemed to let up A LOT like it wasn't leaving too much on my pad like I had been seeing. But I all of sudden just started having a good amount of blood again whenever I went to the bathroom, with really bad cramps, and my back is killing me. They told me whenever I went to the doctors a week & a half ago that my levels were almost all the way down, and I should be fine the rest of the time. And that I could still have a little bleeding. But I thought I was finally finishing up until just a little bit ago. I feel like it's NEVER going to end, how long did some of y'all bleed after miscarrying? It's making me worry, and I just feel so alone and lost because I have no one to talk to since none of my family has gone through a miscarriage, and my husband is gone for another month since he's military. Ugh. When's it going to end?
