Iron Infusions

Patty • Mom of two baby boys & baker.
I have been prescribed 3 iron infusions because I'm so anemic. My hemoglobin is at 8.9, and ferritin 4.6.  I tried taking 65mg of iron 3 times a day and it was horrible how sick I got. Has anyone had an iron infusion? How did you feel after a treatment? Any complications? After birth were you anemic again?
