Gestational diabetes question

Sh

I just got diagnosed and today was my first day following diet restrictions. Does anyone know if it matters if I eat too little carbs? I had a hard time eating enough today. I ate 10 carbs at lunch and 10 at dinner and that’s it. I didn’t have breakfast. I am 30 weeks along and have gained only 4 pounds the entire pregnancy. I am never hungry. All my blood sugar tests today came back under 95 but I’m not sure if that’s just because I didn’t eat enough carbs? Still learning the ropes here. Thanks for any input 😊
