Hcg levels okay?

Katelyn • 29, mother to two daughters, married, expecting third baby!

So I had a miscarriage last December (2018) and just found out I’m pregnant (3rd pregnancy, healthy 7 year old). I’m 4 weeks 1 day today. Went to dr Wednesday at 3 weeks 5 days and they drew blood, called today and said my hcg level was 91. Is that a good number for this early?? I’m just so nervous.
