Help me?

So I had a miscarriage 5 weeks ago my levels dropped to about 30 but then slowly started rising. Last week it was at 77 and this week it’s at 88. So I went in for an ultrasound and there’s no tissue and they don’t see any signs of ectopic. I’m not bleeding and have zero pain or cramping. the OB did say that my uterus looks normal( perfect to be her exact words) and that this can be a new pregnancy. I really don’t want to get my hopes up but has anyone ever gone through this?
