gestational diabetes

hey mamas, just wondering if any previous mother’s or maybe even nurses/doctors here can give me insight. i am 32 weeks and a couple days and i was told i have a big baby, 5 lbs 8oz (for how many weeks i am) i took the glucose test at 28 weeks and passed. Doctor said some people just have bigger babies but i just wanted to know if anybody has experienced this where they passed the glucose test and everything came back normal, then ended up having gestational diabetes or even the opposite where test was normal and u ended up just having a big baby. don’t know if this should be anything to worry about. i will be scheduling an additional glucose test just to be sure. please let me know!!
