Dizzy in shower

Catrina • 25. Married to my other half. 5-15-15. 1 angel baby named River. Daughter named Remington. Son named Journey.
I'm 14 weeks pregnant and while taking a shower today I had a really bad dizzy spell. I scared myself hardcore. 
Anybody else experience this? I'm not exactly sure what happened all I know is as soon as I stepped in the shower i got light headed, weak legs, dizzy, blurred vision. I got out of the shower quickly so I didn't faint. Very scary.
