Time elapsed since the first day of the last menstrual period. If pregnancy was achieved using assisted reproductive

weeks to the conceptional age.
Gestational diabetes (GDM)
Carbohydrate intolerance with onset or first
recognition during pregnancy.
A fasting plasma glucose level >126 mg/dl (7.0
mmol/l) or a casual plasma glucose >200 mg/dl (11.1 mmol/l) meets the threshold
for the diagnosis of diabetes, if confirmed on a subsequent day, and precludes
the need for any glucose challenge. In the absence of this degree of
hyperglycemia patients may be evaluated using a 1 hour 50 gram oral glucose
tolerance test (OGTT) as screening test, or proceed directly to a diagnostic 3 hour 100
gram OGTT .
Gestational diabetes increases the risk of maternal hypertensive
disorders, cesarean delivery, fetal macrosomia, neonatal hypoglycemia, jaundice,
polycythemia, and hypocalcemia. In addition, fasting hyperglycemia may be associated with an
increase in the risk of intrauterine fetal death during the last 4–8 weeks of
Softening of the cervix seen as early as probable sign of pregnancy. Goodell's
sign may be observed as early as six weeks of pregnancy.
