Dizziness in Shower???

Danielle
Ok Ladies, usually I get a little light headed in the shower when I'm on my period... Normal. But I am 6 days late and I took a shower today and BOOM so dizzy, I went blind, had to hop out and cool off. I threw up for a few minutes (usually don't vomit when faint in shower) and I have been having pressure under my belly button...... Been on vacation so haven't had time for a test. But have any of you ladies ever experianced symptoms in the shower before ??
