Very dizzy but negative test?

Question

With all 3 of my previous pregnancy I get low blood pressure and every time I stand up I have to hold on to something for a second. That is happening again. Also I been wanting ice water all day. 
However I took a test today. 9dpo and it was negative. 
Has anyone else has a similar feeling?

Answer

I had light headedness and was always thirsty when I was pregnant. 
It could be a rise in hormones too, ya never know though. 9dpo is still early ☺️🤞🏻
