Your baby is the size of a mango

By the time you reach 19 weeks pregnant, your baby has hit several developmental milestones. You might be surprised to learn that around this week your little one’s adult teeth are starting to grow. They are forming just behind the ‘milk teeth’, which you will see when your baby is about six months old. If you’re expecting a baby girl, her little reproductive system is well established by this point. Her ovaries contain over 6 million primitive egg cells at 19 weeks, which reduces to around 1 million when she’s born. If you’re having a boy, his testicles have formed and started secreting testosterone around week 10 of your pregnancy, and the external genitals are continuing to grow.

If you were to see the foetus this week, you’d see that the skin is quite wrinkly. This is because your little one hasn’t gained too much fat yet. All in good time, though, because in the coming weeks and months the fat stores will increase and those wrinkles will be filled right out. Around this time, the skin starts to produce a greasy coating called vernix. It protects the skin from the amniotic fluid while in the uterus. Most of the vernix comes off by birth, but some babies are born with a little still left on their skin.

Another milestone that occurs when you’re 19 weeks pregnant is that your baby starts to adopt more regular sleeping and waking patterns. They may also wake up to movement and noises. At this point, they will also start growing little nails on their recently formed fingertips and toes.

Through much of the first half of your pregnancy, the foetus’s head has been disproportionately larger than the rest of the body. Now that you’re 19 weeks pregnant, your little one’s body has almost caught up and the size of the body is in proportion to that of the head.

The Size of the Foetus at 19 Weeks Pregnant

At 19 weeks, your foetus is about the size of a mango, and measures around 15 centimetres from crown to rump, and weighs about 240 grams.

Mum's Body at 19 Weeks

At 19 weeks pregnant, your bump is likely growing noticeably bigger and it could even be starting to get in the way of your daily activities. Although by 40 weeks you may find reaching for your shoes impossible, even at this stage your bump may be causing you to rethink those actions you used to take for granted.

For example, if you're a runner, you may be finding the size of your bump at 19 weeks makes this form of exercise uncomfortable. If this sounds like you, it could be time to switch to something like swimming or prenatal yoga.

You might also find you need to adjust what you do to avoid pain. For example, avoiding lifting heavy objects now might help prevent back pain.

As your bump grows, doing exercises that stretch and strengthen the back muscles, wearing abdominal support garments and using heating pads to soothe sore muscles might also help reduce some of the discomfort.

Your growing bump might also be giving you some pelvic pain. If this is you, seek help from you doctor, stay active (but never do anything that gives you more pain), rest whenever possible (so get help with those household chores), take each stair one at a time (or avoid stairs altogether), keep your knees together when getting in or out of a car, sleep on your side with a pillow between your legs and wear flat shoes that provide good support.

As your bump grows, you might be annoyed about some of the things you can't do as easily as before and be bothered by some of the aches and pains of pregnancy. Ask for help whenever possible, and keep in mind that you're almost halfway there and it will all be worth it in the end!

19 Weeks Pregnant: Your Symptoms

Here are some of the symptoms you may be experiencing at 19 weeks pregnant:

  • Brown patches on your face. One of the common symptoms experienced at around 19 weeks pregnant is chloasma or the ‘mask of pregnancy'. If you have these dark or brown patches on your skin, you're not alone. Chloasma affects about half of all mums-to-be. Pregnancy hormones are thought to cause these pigment changes but chloasma can be made worse by sun exposure, so it's a good idea to wear a hat or stay in the shade. The good news? The dark patches will likely fade within a few months of you giving birth.

  • Dull or sharp abdominal pain. As your uterus grows the ligaments of your abdomen stretch to accommodate your bump. As a result, you might feel ‘growing pains' called round ligament pain. This often feels like a sharp or dull pain on one side of your lower abdomen. Rest usually offers the best relief. Call your doctor if the pain is severe or if it's accompanied by any other symptoms like fever or bleeding.

  • Heartburn and indigestion. If you experience a burning sensation in your chest, bloating or nausea after eating a big meal, it could be heartburn or indigestion. As the foetus grows, your stomach has less space and as pregnancy hormones loosen your muscles stomach acid can enter your oesophagus. What should you try to combat heartburn and indigestion? Eat smaller meals, avoid anything too rich or spicy, avoid caffeinated drinks like coffee and energy drinks and sit up straight when you eat.

  • Constipation. Feeling blocked up is a common symptom but that doesn't make it any easier to cope when you feel bloated and achy. Exercising and staying well hydrated can help ease constipation, as can eating high fibre foods. Go for foods like beans, lentils, wholegrain bread, and lots of fruits and vegetables.

  • Swollen gums. During pregnancy, changing hormone levels can increase the amount of plaque on your teeth. This can irritate your gums making them swell and bleed. Brushing your teeth regularly and avoiding sugary snacks can help reduce plaque build-up, but it's also worth visiting the dentist for expert advice.

  • Incontinence. Your body is getting ready to give birth and, as result, your muscles are made to relax by pregnancy hormones. The muscles that support your bladder can also loosen, leading to a little bit of pee escaping when you laugh, cough or sneeze. Practicing pelvic floor exercises regularly might help, but you might also want to chat with your midwife for some extra advice.

19 Weeks Pregnant: Things to Consider

  • Exercise is super important during pregnancy – just don't overdo it. There are many benefits. It will help you adapt to your growing size, it will help you cope with the physical challenges of giving birth, and it will help you get back into shape after your baby is born. It might also help reduce feelings of stress. You can keep exercising and doing your usual daily activities as long as it still feels comfortable. Walking, swimming and yoga can be great choices at 19 weeks pregnant. Don't forget to warm up, stay hydrated during and after exercise and to let your instructor know that you're pregnant if you're doing classes. Experts recommend avoiding exercises that involve lying on your back as your bump can press on blood vessels making you feel faint. They also recommend avoiding contact sports or dangerous activities that can result in injury. If you're in any doubt, talk to your doctor or midwife about the right form of exercise during your pregnancy for you.

  • As your bump gets bigger, you may find it's getting in the way of a good night's rest. Sleeping on your back from the second trimester onward puts weight on your spine and back muscles, and it may also compress major blood vessels, which can leave you feeling dizzy. Instead, try to sleep on your side with both legs bent and a pillow between your knees. You can also put a pillow under your belly. If you wake up in the middle of the night on your back, just go back to sleep on your side. If you find it hard to sleep through the night, try to get some naps in during the day. Also, avoid caffeine in the evening, and try some relaxation techniques and creating a more serene atmosphere in the hours before you plan to go to bed. Learn more about sleeping while pregnant to enjoy a better night's sleep. If you think your sleeplessness might be caused by something more serious, always chat with your doctor – they'll be able to provide some helpful advice.

  • In the coming weeks and months one of your friends or family members will likely start organising your baby shower. They might have some questions for you about what you would like and who you would like to be there. They might also ask you to set up a baby shower gift registry so that the guests will know what to get you that you will actually love and use. Take a look at our registry checklist for inspiration on what to include so that you're prepared.

  • You might like to research hypnobirthing and book a course in the coming weeks. Hypnobirthing is a childbirth education course that focuses on teaching things like self-hypnosis, controlled breathing techniques, and relaxation exercises that can help your birth experience be a more peaceful and calm one. Ask mums in your area for tips on where to find a course, or ask your doctor or midwife to recommend a good one.

19 Weeks Pregnant: Ask Your Doctor

  • What can be done about itchy skin?

  • Would you benefit from using a pelvic support girdle and where can you get one?

  • Can you get access to a physiotherapist for back, hip or pelvic pain?

19 Weeks Pregnant: Your Checklist

  • With any luck, you might have the second trimester energy boost. Use it to get creative and choose what colour you’d like to paint the nursery and start collecting nursery decoration ideas.

  • If your clothes no longer fit your growing belly, it could be time to switch to maternity wear. Ask friends or family members who’ve had children if they have anything to spare, or ask your midwife for recommendations on where to buy affordable maternity wear.
