Miscarriage Question

I was told Saturday I was miscarrying. I had a bleed for about 1 hour then nothing. My levels on Saturday morning were 608 my levels on Tuesday was 86 I go in next week to get my levels checked again. My question is, is it not good to have no bleeding during miscarriage? I'm patiently waiting, for my levels to have dropped that fast, that low and no bleeding it's really worrying me. The nurse never called me back today so hopefully tomorrow she will. Am I freaking out for nothing?
