Is this what a blood sugar drop feels like?

Samantha

I’m 36 weeks and I had an appointment today (ground b test) so they took blood. I didn’t have breakfast like I normally do. Anyways I ate when I left and felt fine. Once I got home all the sudden I felt extremely sick and shaky and broke out in a cold sweat. All I could think about was an apple I had in the kitchen so I stuffed my face with chocolate and fruit and now I feel better?????? Lol it was just weird how quickly I felt so AWFUL
