Your baby at 5 weeks pregnant

What's happening in there

• Your baby is the size of an citrus seed.
• You’re into the first trimester.
• The countdown continues: you’ve got 35 weeks to go!

What happens during the 5th week of pregnancy?

• You missed something: If you haven’t already noticed, you may be late with your period. It’s time to head to the pharmacy or shops and pick up a test kit.
• Hello hormones: You’re starting to get the first hormonal effects, whether they’re sore breasts, fatigue or that dreaded nausea you’ve heard so much about.
• Baby's forming: The placenta’s under construction and in a position to start providing nourishment to your little creation.
• Little layers of wonder: This week, the embryo divides into three layers called germ layers. The outer one will become the brain and nervous system, skin, eyes, ears, and hair; the inner layer will form the lungs, intestines, bladder, and liver; and the middle layer will become the circulatory system, reproductive system, kidneys, cartilage, muscles, and bones. A healthy diet will nourish your baby’s growth, complemented with a prenatal vitamin that has DHA to fuel brain development.

Week 5 pregnancy symptoms

During week 5 of pregnancy, your body is changing quickly. As your baby grows, you will too, and there are certain pregnancy symptoms you may experience at this time.

3 expert tips for a healthy and safe pregnancy

Being 5 weeks pregnant is an important time for you and your baby. Here’s some more expert-recommended advice on how to adjust to this new stage and keep you and your baby safe.

1. Getting enough protein: Protein is important for your baby’s development, particularly your little one’s brain. Make sure to get three servings of protein every day, which is equivalent to about 75 grams.
2. It's time to make a prenatal appointment: Your doctor can screen you and your baby for any health risks and make sure you’re doing everything you can to nourish the life growing inside you. Check with your doctor about any medications that you’re taking. Some might be OK, but others could be harmful to your baby and cause serious birth defects or miscarriage.
3. Morning sickness doesn't stick to any clock: Expect to feel symptoms at any time of the day—so here are some tips to help provide some relief over the next few weeks.
