Low blood sugar

My mom has a machine that I have been using. If I don't eat every 2 hours my sugar drops. I keep checking it after I have already ate and it's been about 77-80. Just wondering if anyone else has had hypoglycemia during pregnancy and what did dr do or how did you get diagnosed? I'm worried it's only going to get worse. I feel completely horrible when it gets low and sometimes eating doesn't help. I'm definetly going to bring it up at my next appointment. Thanks in advance!
