Dizziness and fainting

Claudia • Mummy to William James 8th March 2015
Hey ladies
Last night I was out for dinner, sitting down and just talking to my husband. 
I felt really dizzy just as our starters came I went and got some fresh air and I felt ok. I came back and ate all my meal. Then we were just waiting for our bill and I completely blacked out. Went to the hospital but my bloody pressure was fine, my blood sugar was fine....basically they couldn't find anything wrong and baby was still happy. 
Anybody else experianced this?
I am still not feeling great or "myself" today. 
Just taking it easy.
