hCG levels are 4 weeks 3 days

Kim • Mom to one beautiful daughter born 8/13/18. Expecting rainbow baby 11/1/20 💕💙

I had a blood test to check my progesterone and hcg today at 4 weeks 3 days. Progesterone was 18.30 - dr said was normal. Hcg was 887 and she’s checking them on Friday again to see the increase. I’m so nervous! This is my 3rd pregnancy. I have an 18 month daughter. First positive after mmc at 8.5 wks 6 months ago. I’ve never checked my levels so I don’t really know what to expect. Does this number seem low? Anyone have a normal pregnancy with this range at 4 wks?
