The past couple of days I have been having dizzy spells, sometimes feeling like that for many hours. It's not the same as hunger dizziness and I don't feel sick at all or have a headache. I feel quite woozy especiaally when I am bending over and come up.

I told my SIL and she said that her and some girls in her mum's group all had the same thing and it was because of hormones because of bfeeding so they all switched to formula. Does this sounds right?
