Glucose test

I took a glucose test back when i was 11 weeks, & i cant help but think im going to take another. I passed with flying colors, but im now 23 weeks & i feel like on my next visit dr will tell me its time again. Has any other momma taken the test twice? Im on the heavier side so idk if dr had me take it early to see if everything is ok, baby boy is perfectly healthy & is growing due to the weeks i have. Also diabetes runs on both sides of my family as well as my husbands. But i need some help on this, havnt heard anyone else take the test twice unless they fail then do the 3 hr test.
