Hypoglycemia...???

So I’m only about 5 1/2 weeks pregnant but this past week I’ve been noticing that if I go more than a couple hours without eating I get really weak and shaky I feel like I can’t think straight and could pass out. I’ve never experienced this in previous pregnancies. For instance yesterday I had Mac and cheese and a bowl if Cheerios w/ blueberries for lunch around 1:00ish and then around 4 I had a few bites of a cheese sandwich and chips but didn’t eat much because I wasn’t feeling really hungry and then come supper time and I was giving my daughters a bath while my husband was cooking chicken fajitas around 6:30 and I felt so sick almost disoriented and weak. I literally inhaled 2 fajitas I couldn’t wait for everyone to sit and eat together! I started to feel better not long after... but this happens a lot lately. From what I read online it seems like it’s hypoglycemia( I’m not diabetic according to my doctor.. I just recently had my blood work done and my blood sugar tested ) just wondering If anyone has experienced this? I’m feeling nervous and not sure if I should make an appointment with my ob?
