Cramps normal as the others have said.

I got dizzy with low blood pressure and low iron. Try eating more red meat and also to help with the absorption of iron into your blood you will need to increase your Vit C, so also eat more citrus (mandarins are my fav at the moment!) and drink plenty of good OJ.

If it gets to the point of getting in the way of your normal activity then maybe just ring up your GP/OB/MW and ask - you might need to have your BP and iron tested.

GL!
