Swaying and dizzy normal?

Yesterday in the evening I suddenly got really tired and dizzy. To the point where my head was really heavy and felt like just lying down. I thought it was sort of odd, but decided to just call it a night.

Today, while at work, I’ve occasionally been getting really dizzy/light headed. And swaying too. It gets worse as the day progressed. I’m seeing my doctor on Friday, but curious if anyone else has had this happen so suddenly too.

I’m not sure if it has anything I do with it, but I have Thrombocytopenia since before the pregnancy. (Low platelets)

I’m 9 weeks.
