What Are the 3 Trimesters of Pregnancy?

Pregnancy is divided into 3 trimesters of pregnancy, each lasting around 12–14 weeks.

From Which Week Does the Third Trimester Start?

Many parents ask, from which week third trimester starts?

You may notice:

• Increased belly size

• Practice contractions (Braxton Hicks)

This is also the stage when parents begin preparing newborn essentials at home.

This is an ideal time to prepare newborn cloth diapers, langots, wipes, and bedding essentials to avoid last-minute shopping post-delivery.
