Second Trimester: 14 Weeks Pregnant

At 14 weeks pregnant, you’re now well into the second trimester of your pregnancy, often referred to as the ‘honeymoon phase’.

This stage is characterised by a renewed sense of energy as early symptoms like nausea and fatigue begin to fade. You may also feel more at ease as the risk of miscarriage significantly decreases.

This week is full of exciting developments for both you and your baby as you will soon find out (or already have!).

Let’s dive into the incredible changes happening during this pivotal stage of pregnancy.

Your Baby at 14 Weeks of Pregnancy

This week marks significant progress in your baby’s development, with milestones that bring them closer to looking and functioning like a newborn.

Now that you’re 14 weeks pregnant, your baby is about the size of a kiwi fruit, measuring between 8 and 9.3cm in length and weighing approximately 25g.

Here are the exciting changes going on with them without you even knowing:

Breathing: While your baby doesn’t breathe air yet—oxygen comes from your blood via the umbilical cord—he is practising the movements needed for breathing. This ‘rehearsal’ is essential for life outside the womb.
Facial Expressions: Your baby’s movements are becoming more fluid and controlled as connections between the brain, muscles, and joints develop. He can squirm, stretch, and even make facial expressions like frowning or squinting.
Body proportions: Although the head remains relatively large, the body is starting to catch up, creating a more balanced appearance. This proportional growth will continue throughout pregnancy and beyond.
Sex development: For girls, the ovaries are moving into the pelvis; while in boys, the prostate gland forms, and the testes continue to develop in the abdomen. External genitalia progress, though it may still be hard to determine the sex on an ultrasound.
Lanugo Hair: Fine, downy lanugo hair begins to grow all over your baby’s body, acting as a protective layer for the delicate skin submerged in amniotic fluid. This hair typically sheds before birth.
Hair growth: Hair on the head and eyebrows also starts to form, adding to your baby’s human-like appearance.

Your baby’s placenta is now fully functional, taking over the vital role of providing nutrients, oxygen, and protection while removing waste.

Your Body at 14 Weeks of Pregnancy

In this ‘honeymoon period’ of pregnancy, symptoms like nausea and fatigue begin to fade. However, there are still notable changes and challenges.

Now that you’re 14 weeks pregnant, your uterus has grown to the size of a small melon. It’s moving upward, reducing pressure on your bladder, which may provide some relief from frequent urination.

Other than that, here are some other things you can expect your body to be doing at this stage of pregnancy:

Heartburn: As your baby grows, your digestive system can feel the squeeze. Heartburn is a common complaint during this time, caused by hormonal changes and the physical shift of organs.
Skin tags: Hormonal fluctuations may cause skin tags or changes in moles. While most are harmless, be sure to report any irregularities to your healthcare provider.
Haemorrhoids: Increased blood flow and the pressure from your growing baby can lead to haemorrhoids. Prevent these by eating fibre-rich foods, drinking plenty of water, and avoiding prolonged sitting or standing.
Bleeding gums: Hormonal changes during pregnancy can make your gums more sensitive and prone to bleeding. Pregnancy gingivitis is common, but you can prevent it with proper oral care. Brush and floss regularly, and visit your dentist for check-ups.
Sleep issues: As your belly grows, sleeping on your side with a supportive pillow can help you find a comfortable position.

Pregnancy Weight Management

If you were overweight before pregnancy, you’re not alone—up to 38% of pregnant women fall into this category. Gaining weight steadily and within recommended guidelines is crucial for a healthy pregnancy.

Obese women are advised to gain only 5–9kg (11–20 pounds) throughout their pregnancy.

Here’s what you can do to maintain a healthy pregnancy weight:

Reduce sodium: Cutting back on salty foods can help manage your blood pressure and prevent dangerous conditions like preeclempsia.
Stay active: If your doctor hasn’t mentioned it yet, talk to them about exercise. At 14 weeks pregnant you should avoid excessively strenuous workouts. Moderate, pregnancy-safe exercise like walking or prenatal yoga can help you maintain a healthy weight.
Eat smart: Focus on whole grains, lean proteins, low-fat dairy, and plenty of fruits and vegetables.

If you haven’t already, now might be the time to invest in maternity wear. Comfort becomes a priority as your regular clothes may no longer fit properly.

Never go on a ‘diet’ during pregnancy.

Many women decide to go on a caloric deficit during their pregnancy to ensure they get their figure back after childbirth. You don’t need to starve yourself.

Choosing nonfat or low-fat products, meats, grain products, fruits and vegetables is enough to maintain a healthy weight.

Enjoy the Ride

At 14 weeks pregnant, you’re well into the second trimester and starting to feel the positive shifts that come with it.

Your baby is developing rapidly, practising movements and expressions while your body adapts to the exciting journey of motherhood (for better or worse).

Take time to enjoy the ride even with all the bumps, because the journey is just as important as the destination, mummies!
