What is developing at 6 weeks

Your baby is about the size of a sweet pea, and a flickering heartbeat may be visible on an early ultrasound this week. The neural tube is closing, and small buds that will become arms and legs are beginning to appear. Facial features are also starting their earliest development.

Your body

What you may be feeling

Morning sickness, which can strike at any time of day, often begins around now and tends to build over the next few weeks, along with fatigue and breast tenderness. You might feel more emotional or notice food aversions and cravings. These shifts are driven by rising hormones and are a normal part of early pregnancy.

Tips for week 6

Eat small, bland meals throughout the day and keep crackers nearby if nausea hits hardest in the morning. Stay hydrated and rest as needed, since your body is working hard. If you have not had your first prenatal visit, now is a good time to call, since most practices like to see you between 8 and 10 weeks.
