Pregnancy week 15

Your baby’s development

By week 15 your baby is about the size of an apple. One notable change is that the skeleton keeps hardening, as cartilage gradually turns into bone. The skin is still thin and almost transparent, so the blood vessels underneath are easy to see. A fine, downy layer of hair called lanugo begins to cover the body and later helps protect the skin. The eyelids stay closed, yet your baby starts to sense light; a bright light shone on your belly may make the head turn away. The arms and legs now look more in proportion with the rest of the body. Your baby moves a lot, opens and closes the fingers, and practises swallowing and sucking. Most people cannot feel these movements yet, because the baby is still small and has plenty of room. Every baby grows at a slightly different pace, and the measurements given here are averages. Development moves at its own pace in every pregnancy; your doctor interprets ultrasound measurements, and small differences are usually ordinary.

Changes in the mother

Many people feel more energetic and settled this week, and the nausea of the first months often fades. Hormones and a larger blood volume can still cause small discomforts. A stuffy nose, occasional mild nosebleeds and gums that bleed when you brush are common and usually harmless. A soft toothbrush helps, and it is a good idea to tell your dentist that you are pregnant. Your belly may start to show, which can mean changing your wardrobe and is entirely normal. Some people notice the first flutters around now, like a bubble or a tiny wing beat, but not feeling anything yet is no reason for worry. Take some time for yourself, try to stay active and drink enough water. Anything that puzzles or unsettles you can be raised at your next check-up.

To do this week

• Talk with your doctor about the triple or quadruple screening test (usually weeks 15–20/22).
• Plan your second antenatal visit (usually weeks 18–24).
• See a dentist for a gum check.
• Set up a routine of short daily walks.

Tip for the partner
