Hcg stress

Hey ladies once again anxiety is up. I go in for my third hcg level. At 16 dpo I was 229 at 18 dpo I was 860 now I'm  22 dpo and am hoping to get even higher results so I can get an ultrasound next week. I know I shouldn't stress the dr says everything is going well, but I think I am going to until I pass 12 weeks since I already lost 4 angels. Any other mommies in my boat?
