Hey Tegan

I'd do what the girls have said but your BP sounds ok to me. Christy said drink heaps of water, I'd do that. Perhaps your iron is low, so I would up the red meat (if you eat it) and the green leafy vegies.
The other thing to keep in mind is GD. Often ladies have the symptoms you describe after they have eaten something high in sugar. have you had the GTT yet? if you have, was it the 50g or the 75g?
Latest research shows that many women come up as 'within normal limits' in the 50g but when they do the 75g, registers as GD. (That's what happened with me). Anyhow, I hope that you get some answers soon it's exhausting looking after a toddler when you feel awful in yourself
