I have been having dizzy spells over the past few days. It just hits me all of a sudden. I had a doctors appointment yesterday (not related to this,) but I was dizzy then and my blood pressure was fine). I am a diabetic but I ve checked my sugar and it s not low or too high. This isn t a feeling I get when my sugar is low. I get dizzy whether I m sitting or standing and it will last for a few minutes and go away but not for too long. When I get dizzy, I feel as if my eyes are going to cross but they never do. At times I feel like I m going to pass out. Any tips on what could be going on? *there is also a chance that I could be pregnant but I ve taken multiple home tests (including one last night) and they all say negative.
