Extremely dizzy at 9 weeks.

So I have had some serious afternoon and evening dizziness that I can't seem to get rid of. I have been downing the protein and water as much as possible (I'm a huge water drinker to begin with) and it's not helping at all, constant room spinning feeling. I have an ileostomy which could possibly be the culprit but I wanted to know if any other moms to be are going through this and have any tips.
