75G OGTT test

Hello mommies! Ask ko lng po kasi nag 75G ogtt nako nung early trimester kasi ebi ng OB ko pra mlaman early if high risk pregnancy ba ako since may family history of diabetes kmi. Pero thank God normal results ko even ibang lab tests. Ipapaulit pa kaya n Doc yung OGTT ko ngyon 2nd trimester or no need na? May same case ba dito?
