I'm 26 weeks and for the last week or so i've been getting really bad dizzy spells, this morning was the worst as I nearly fainted. Basically I feel like all the blood is draining down to my feet, my heart races and I get blurry vision. I tend to only get this in the morning even though I've eaten breakfast and drunk a pint of water. I do tend to get a racing heart quite a lot though especially when lying down at night (I lie on my side and not my back).
Anyway is this normal and is it worth calling my mw? I am due to see her in a week and half anyway so don't want to waste her time if this is normal but at the same time I hate feeling like this and I'm worried I might actually faint on the street when walking to/from work.
