Showers make me dizzy.

Hello. I'm 9 weeks and a few days today. Every time I shower I get really dizzy and light headed and nauseas. Even if the shower is cold. It's so bad that by the end of my shower I'm leaning on the wall and sitting in the tub. And I only take 10-15 minute long showers because I know they make me dizzy. I don't have morning sickness. I've thrown up once the whole time I've been pregnant and it was because of bad food I ate. I don't know what to do because I obviously can't not shower but they make me so sick. Help. :(
