19 Weeks Pregnant: Your Baby’s Development
Extra eggs. If you're carrying a girl, her little reproductive system is already well established. The vagina, uterus, and fallopian tubes are all in place, and the ovaries contain more than 6 million primitive egg cells. When she is born, that number will have dropped to about 1 million.
Male genitalia forms. 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.
Second skin. Around this time, the 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.
Baby sleep cycles. 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.
New nails. 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 the size of a mango, measuring around 7 inches in length, and may weigh between 6.5 and 8 ounces. 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
Funny face. 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. 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 center 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.
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.
19 Weeks Pregnant: Ask Your Doctor
If you’re curious about how your little one is developing, ask your doctor about the size and position of your baby when you’re 19 weeks pregnant.
Ask your doctor about the best exercise plan for you at this stage of your pregnancy.
If you have severe back pain or pain in your abdomen, tell your healthcare provider, especially if you have any other uncomfortable symptoms like painful urination or fever.
