failed glucose

!!! so i failed my 3 hour glucose test (first and only test i took) and i’ve been testing my blood sugar until my next apt. everytime i’ve checked my sugar it’s never been over 105. i haven’t changed my diet at all, whatsoever. i still eat how i normally eat. they haven’t told me i’m gestationally diabetic yet. they said we would talk at my apt after looking at my levels. i actually have been having LOW blood sugars too. today i tested 2 hours after breakfast and it was only 55 😅 im just curious as to what this means. i failed the test for high sugar but my sugar levels have been on the lower end?
