Fun new symptom- hypoglycemia ?

All of a sudden at work this afternoon my vision went blurry and I couldn’t focus on my conversation with a coworker. I also got super hot and sweaty all at once. It lasted about 5 min. I called my midwife and she said low blood sugar episode (I ate lunch at 11- pizza Thursday lol). Haven’t had my gestational diabetes test yet. Has anyone else experienced this? I ate a granola bar, some pb, and had some soda and feel better, but worried at how fast it hit me.
