Hcg levels? Anybody familiar with this?

So on 6/15 I got my BFP and last Thursday I had my first prenatal appointment. 
They only did a confirmation urine pregnancy test (positive) and some blood work. So I called back today for my results and was told my Hcg Quant. was only 4.88. The tech. didn't tell me what this meant as far as how far along I am, but said this could mean a "bad" pregnancy. Every time I try calling the office I get the answering machine with no returned calls from any of the staff. 
I guess my question is this:
Does the 4.88 level sound right for only being 5 weeks pregnant at the time of the blood draw (which I think* I am)? My next appointment isn't until July 14 and that is when I will have my ultrasound, but the MA on the phone said this low level could mean a "bad" pregnancy. I've already had a miscarriage in the past so I don't believe it's too far of a stretch for me to kind of be upset already hearing negative news this early on.
