I was going to say anaemia too. I had slight anaemia diagnosed from my booking in bloods and the midwife warned me that if I was excessively tired, had palpatations or was breathless then it was a sign my iron levels were dipping and I would need supplements. I've had a few of these symptoms at various points but have started taking my pregnancy tablets regularly and am feeling a bit better so hopefully won't need iron tablets for a few more weeks. Your midwife may well want to check your blood.pammie said:I have suffered palpatations and short of breath and turns out am anemic. but my blood pressure was normal.
