Can I have a gestational diabetes test after 28 weeks?

Sara

Unfortunately, I will not have insurance for a few weeks since my dad is transferring to reserves in the air force. So Tricare will be changing. I am currently 25 weeks and 5 days and he says I likely won’t have insurance for 10 days or maybe longer. Is it okay to have the test done by 30 weeks? I feel like I will have insurance by then.
