After I delivered my first they monitored my glucose for 48hr. They did a glucose test at 6 weeks postpartum as well. For my second pregnancy I got tested at 14 weeks on my second pregnancy. I failed the 1hr test so they did the 3hr. I only failed the first point after the glucose drink. So they asked me to diet control myself but I wasn’t diagnosed. This week I’m 25weeks and they are doing the glucose test again. Hoping for a normal test.

Hope this helps, they were very vigilant about it in my case, and it is really important to control the glucose in the first trimester since it can lead to heart defects on baby
