Welcome to Week 16 of your pregnancy. Your baby is developing rapidly, and your body is going through trimester-specific adjustments to support fetal growth. Knowing what changes occur during this week helps you prepare for what lies ahead.
Your baby is currently in the Second Trimester of growth. At week 16, the fetus is roughly the size of a Avocado, measuring 11.6 cm in length and weighing 100 g.
During this stage, your body is adapting to hormonal releases. Common symptoms include:
Decreased morning sickness, starting baby bump, mild backaches, skin pigmentation changes, or nesting energy spikes.
We recommend tracking these daily in our companion app to generate clinical logs for your doctor.
