Is it normal?

My miscarriage began on the 21st spotting ended in the moring on the 29th and on the 30th I had an ultrasound to confirm that I had finished miscarrying and I did. They also did blood work on the 30th and my hcg was 567. On December 8th my hcg was 388 yet I started my period later that day. I didn't think you could get your period until after your hcg goes to zero. I am now on day 7 of heavy bleeding and it doesn't seem to be lightening up any also I have been having pelvic pains that are different than cramps if that makes any sense. its almost like my insides feel bruised like it hurts to sit certain ways even and I know it isn't from sex because the pain started with the bleeding. I'm also can't stand the smell but I'm not sure if the smell is normal or not because my sense of smell is still very heightened because my hormones are still high. I'm beginning to think something is wrong but need advice or maybe experiences. This is my 8th miscarriage and I have never experienced this.
