I am 12 weeks pregnant. I am a very active 29 yr old with two girls ages 5 and 3. I take multivitamins, choline and inositol, fish oil, folic acid. I have shown to be slightly anemic with past pregnancies. I need to remember to take my iron supplement or eat more red meat. I haven t been faint or dizzy. Just the typical slight nausia and fatigue. When I exercize I feel great. Two days ago I started getting a cold, pins and needles sensation in my foot. The next day it went to both feet and up to my calves. It seems to not be noticeable if I am in the middle of exercize or my feet are up and very warm. But I cant exercize all day, and I can t put my feet up all day. Could this be a iron deficiency problem or do I need more B-12 perhaps? Thanks for your advice.
