At 27 weeks of pregnancy, you are 6 months and 3 weeks along. Still, there’s no real need to calculate gestational age in months. Healthcare professionals always measure pregnancy by weeks, since it is more accurate.

Prenatal visits are still scheduled monthly at this point, but starting at week 28, they become weekly. Between weeks 24 and 28, doctors typically order tests to screen for gestational diabetes, in addition to the regular monthly checkups.

At 27 weeks, the baby is about 14.5 inches (37 cm) long and weighs around 1.9 pounds (875 g). This is also a good time to start discussing labor, postpartum birth control options, and breastfeeding with your doctor.

If there is any uncertainty about how many months is 27 weeks, it is best to consult an obstetrician. This specialist can closely monitor the pregnancy and detect possible complications early.
