Hi, I'm new here. I saw my doc today who thinks vit b12 deficiency a possible cause for my severe fatigue. She's sent me for follow up blood test to check vit b12, folate & ferritin levels amongst others. Having read up on the symptoms PA seems to fit and my dad had b12 deficiency so might be that it runs in our family too. Its all new to me and just trying to inform myself, doc mentioned about injections if blood results show deficiency but wasn't sure if ok in pregnancy, wondered if any of you know? I've also been reading about sublingual supplements and have ordered some of the jarrow brand ones which had good reviews on amazon, anyone had any experience of these? I'm 7 months pregnant and v desperate to feel better so any advice gratefully received!
