It doesn't happen during every period, but this time it's bad enough I can't even drive. I've had dizzy spells where I stumble. A few have lead into blackout spells but I come to quick enough that I never have fallen over. There is no cramping at all. I rarely cramp on my periods. But I'm having spells of feeling so weak I can't hold my head up. I tried to eat something and that's the only time nausea hit and I couldn't eat more than a few bites. I'm not myself and others around me have notices it. And now, suddenly, I'm getting sudden bursts of headaches. I do not have insurance so I'm trying not to go in. Does anyone else have these issues and what is it and what can I do to help?
