Measurements are approximate. Healthy babies grow at different rates.

Baby development

Kicks and stretches may feel stronger and more frequent.
Developing bones harden and tooth enamel forms below the gums.
The head grows to accommodate rapid brain development.

Your body

Backache, foot swelling, frequent urination, itching, constipation, and poor sleep are common.
The uterus feels more crowded as the fetus grows.
Urinary symptoms can be confused with normal frequency, so pain or fever matters.

This week's checklist

Attend childbirth education if it is part of your plan.
Explore realistic childcare and postpartum support options.
Keep nursing pads available if colostrum leakage is bothersome.

Call your care team

Contact maternity care immediately for reduced movement, bleeding, fluid leakage, or regular painful contractions.
Call for burning urination or fever; seek urgent help for severe headache, vision changes, chest pain, fainting, or severe abdominal pain.

Every pregnancy is different. Use this guide for general education and follow the advice of your own maternity care team. Do not delay urgent care because of something you read here.
