midtrimester

Weeks thirteen through

Midtrimester refers to the middle third of pregnancy, roughly weeks 13 through 27.

The term appears most often in medical contexts discussing procedures, development, or complications during this period: midtrimester abortion, midtrimester ultrasound.

Less common than the standard term second trimester, but useful when emphasizing the middle portion of gestation as a distinct phase.
