I am 27 weeks pregnant now. My hemoglobin level is 7.8. Prenatal and iron supplements make me to constipated. I was told to see a hematologist by my ob/gyn. IS this a dangerous level and is there anything I can do on my end to raise my numbers. I am take two iron supps a day by vitamin code and 6 chlorella supps I have also increase liver and other red meat in my diet and I am juicing green veggies I am feeling better.m but should I be worried.
