Can't stand this dizziness...

I went and had a hearing and ear pressure test done yesterday in the hopes that it might give me some reasons for the dizziness. Nope-they came back normal. I have had dizziness for almost 3 weeks. In the past it was maybe a week at a time and then it would go. So I was looking up dizziness again, when I cam across a site talking about dizziness during pregnancy. It said that the 1st month of pregnancy it is most common because of the rising hormones. These hormones cause blood vessels to relax and widen which causes low blood pressure and reduces blood flow to the brain which can cause dizziness. The last couple of doctor visits I've had I've been surprised at my lower BP. I always run 120/70. The last couple of times I've been 100/50. I know that everyone shows symptoms at different pressures. Has anyone who's had dizzines noticed a correlation between BP and their dizziness. I know I'm grasping, but I can't deal with this anymore...sooo frustrating.
