blood sugar issues?

any one experiencing blood sugar issues? I'm only 8 weeks and 5 days and I don't remember being so dependant on eating at certain times with my last two pregnancies. I need to make sure I eat every few hours or my blood sugar drops. Then tonight, right after supper, I felt really off and my vision got blurry. It went away after about an hour but I had to drink a bunch of water and lay down. after a quick google it sounds like a blood sugar spike. Isn't it too early to develop gestational diabetes? I wasn't diabetic before, i was in perfect health when this baby was conceived, aside from being obese.
