Dizzy and spacey during period?

Hello all,

Ever since I came off birth control 2 years ago I’ve had regular periods, but the week before and all throughout my period I get really dizzy and just feel generally spacey and ‘off’. It’s almost as if my eyes can’t focus and my head feels full, like when you are starting to get a cold.

I take iron and probiotics every day, and my periods aren’t heavy or particularly painful.

Any ideas, or anybody else feel like this?
