19 Weeks Pregnant: Your Baby's Development

At this point, your baby's reproductive system is developing quickly. If you're carrying a girl, the vagina, uterus, and fallopian tubes are all forming, and the ovaries contain more than 6 million primitive egg cells. When she is born, that number will have dropped to about 1 million. If you're having a boy, his testicles have formed and have been secreting testosterone since about week 10 of your pregnancy. The external genitals are continuing to grow.

You may not know yet if you're having a boy or a girl, but you can get prepared by checking out our Baby Name Generator for name ideas.

Around this time, your baby's skin starts to produce a waxy coating called vernix caseosa. Made of oils secreted by the skin, dead cells, and lanugo (the fine hair that covers the body), vernix protects your little one's skin from the effects of floating in amniotic fluid. Most of it will disappear before birth, but preterm babies are often born still covered with a lot of vernix.

Your baby is also getting into a rhythm that includes more regular periods of sleep and being awake. Around the time you're 19 weeks pregnant, your little one begins to sleep and wake in more regular patterns and may also wake up to movement and noises.

Another new development? Your baby is also growing little nails on those recently formed fingertips and toes!

How Big Is Your Baby at 19 Weeks?

At 19 weeks, your baby is about the size of a mango. If you have a checkup this week (or sometime soon), your healthcare provider will measure the height of your uterus to check on your baby's growth.


Mom's Body at 19 Weeks

When you're 19 weeks pregnant, how many months along are you? You're now midway through month five. At this point in your pregnancy, you may feel more aches and pains as your bump grows, and your feet might swell up a little. Or you may experience dizziness, nasal congestion, and backaches. Still, you'll be thrilled when you feel a flutter or a kick as your little one grows and starts getting active.

19 Weeks Pregnant: Your Symptoms

  • Skin changes. The dark patches you may have on your nose, cheeks, and forehead are a common condition of pregnancy called chloasma, or the "mask of pregnancy." Hormones are to blame for this blotchiness, which affects some pregnant women. Pregnancy hormones are also responsible for the linea nigra, the dark line running down your belly to your pubic bone at around 19 weeks pregnant. Both chloasma and the linea nigra will gradually fade after you give birth. Exposure to the sun can darken the pigments in your skin even more, so be sure to use sunscreen or stay in the shade.

  • Round ligament pain. As your uterus grows, the round ligaments supporting it have to stretch. Occasionally, these stretched-out ligaments will cause a sharp pain or a dull ache in your lower abdomen, usually on one side or the other. It's probably most noticeable when you change positions or get up suddenly. Rest usually offers the best relief. Call your doctor if the pain comes with a fever, chills, painful urination, or bleeding, or if the pain is severe.

  • Lower back pain. Backaches are among the most common pregnancy complaints, especially from the halfway point of your pregnancy onward. This is due to your growing uterus and the hormonal changes going on in your body. As your centre of gravity shifts, your expanding uterus strains your back muscles. You can take some measures to ease back pain, such as doing exercises that stretch and strengthen back muscles, wearing abdominal support garments, and using heating pads to soothe sore muscles.

  • Congestion and nosebleeds. Around 19 weeks of pregnancy, you may find yourself reaching for the tissues with a stuffy or runny nose. Your hormone levels have increased, and your body is making extra blood, which can cause the mucous membranes in your nose to swell up, causing congestion and maybe even nosebleeds. Try using saline nasal drops or a humidifier in your home for some relief.

  • Dizziness. You may feel faint, dizzy, or lightheaded at this stage of your pregnancy. Lie down if you're feeling faint, and stay hydrated.

19 Weeks Pregnant: Things to Consider

  • Get moving. Exercise is beneficial for you and your baby; however, it's important not to overdo it. Walking, swimming, and even yoga or Pilates are great choices during pregnancy. When you're 19 weeks pregnant, it's a good time to work on strengthening those back muscles, and exercise in general can help reduce your stress levels, too. Talk to your healthcare provider about finding the right form of exercise during your pregnancy.

  • Sleep soundly. 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 can also compress major blood vessels, which can leave you feeling dizzy. Try to sleep on your side with both legs bent, and place 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 sleeping on your side. Learn more about sleeping while pregnant throughout the trimesters.
