Low hemoglobin/hematocrit

I did my glucose test yesterday and just looked at the results online, and saw I passed the glucose test but have low in the other 2 categories. I know the numbers aren’t too low compared to the range, but has anyone had any experience with this?

I take my prenatals every day (and the whole 2 years TTC), and also take an extra 400mg of folic acid.

I have my next appointment Thursday, and I’m sure the office will call me on Monday. I’m 27+6 today.
