Miscarriage help

Hi everyone,

I went to the er on Monday (9/4) and found out I was having a miscarriage. I had had dark brown blood on my toilet paper when I wiped for a few days before that, but I had thought that was implantation bleeding. I was about 6 weeks on Monday when I heard the horrible news. I didn't actually start fully bleeding until the next day (9/5) and am still bleeding now (9/10).

Anyone know about how long I will be bleeding for? How do I know when AF is back on track?
