Gestational Diabets issue?

For anyone who was diagnosed with GD, I've been having a very strange experience. I failed my one hour test by 15 points according to my doctor's range, and went on to fail my 3 hour, hence the reason i was officially diagnosed.
I have been monitoring my blood sugar for the past few days, and it has never gone above 95 following 2 hours after my main meals! In fact, it has dropped to 68 mg/dL 2 hours following my lunch which consisted of 47 carbs.
I'm just really confused as to how this is happening. Maybe my diagnosis was incorrect? I don't know. Any input would be appreciated.
