Hypoglycemia while pregnant

Anyone else have symptoms of hypoglycemia during third trimester? I get hunger pains and if I don’t eat something within 30 minutes I feel nauseous, hot and clammy feeling then it progresses to dizziness and feeling a little confused. This has just started maybe the last two week around 30 weeks pregnant. Seems like the period that I can go between eating keeps getting shorter. Today I ate breakfast at 7 am and felt hungry at 9 am waited till my normal 10 am snack and by then I was nauseous, dizzy and clammy feeling.
