Lightheaded / faint feeling @ 22wks

Kara

The past week and a half I’ve suddenly found myself having random lightheadedness & dizzy spells. Before I got pregnant I was super prone to passing out when I got blood drawn and the feeling I randomly get now is very similar to that - start getting hot and clammy, lightheaded, ears ringing, lose the color in my face but I never fully pass out. I’ve also had some issues with my arms suddenly going numb/getting tingly. OB said my blood pressure is fine so it could be needing to eat or drink but it tends to happen about an hour after I eat and drink. Has anyone else had a similar experience or have any idea what could be causing this? 😅 my doctor doesn’t seem concerned at all but it has me afraid to leave the house in fear of passing out in public!
