Understanding Your Pregnancy Trimesters

First Trimester (1-12 weeks)

Key developments include organ formation, morning sickness may begin, and first prenatal appointments. This is a critical period for fetal development.

Second Trimester (13-27 weeks)

Often called the "golden period" with reduced nausea, visible baby bump, and feeling first movements. Gender can typically be determined.

Third Trimester (28-40 weeks)

Rapid growth phase with increased discomfort, preparation for birth, and final organ maturation. Regular monitoring becomes more frequent.
