Dizziness

[withay]

Hi all, I was just wondering if anyone else suffers from periods of dizziness? I keep get dizzy spells a couple of days before my period is due. I've had blood tests etc for iron, thyroid, B12 and everything is normal. Before my last lap I almost fainted a couple of times in the days before my period which is when they sent me for an ultrasound to find a cyst. I've been referred for another ultrasound as on assessment with my GP I had a lot of pelvic discomfort (weirdly more central than around my ovaries), I'm just waiting for a letter to make the appointment. I have now been getting dizzy spells away from my period which is strange and I just wondered whether anyone had similar.
