I am 15 weeks pregnant and my doctor had me to take a diabetes test early. not sure why. could have there been signs in my blood work?

Early testing common: Most pregnant women are screened for gdm (gestational diabetes mellitus) at 28 weeks. Those standards have however changed and screening is often done around 16 weeks in women who have had big babies on an earlier pregnancy or are themselves heavier. Regardless, this change to earlier testing is the consequence of seeing more diabetes in more women generally - so too in pregnancy.

Maybe: There are reasons that women get tested for diabetes early before the routine 24-28 weeks of gestation. These are women who may be at higher risk and would benefit from diagnosing diabetes earlier. Some reasons for early testing include glucose in your urine, a high random blood sugar, previous pregnancy with gestational diabetes or a large baby weight, or a strong family history of diabetes.
