Low Hemoglobin?

Alysa

We had ourfirst ob appointment on Wednesday, which was just a nurse's visit and labs. Well I got my results back from the labs today and the hcg looks good. 92,000+ at 8 weeks exactly. The only other highlighted result was that my hemoglobin was low. I'm confused. If blood volume is supposed to increase during pregnancy, shouldn't my hemoglobin be high?
