4 months pregnant baby size: How Big is Your Baby?

The baby weighs the same as a mango at 19 weeks of pregnancy. Your fetus, which is still growing and about 6.0 inches long and 8.5 ounces in weight, is 19 weeks old.
Your fetus is developing the vernix caseosa, the skin’s protective layer, at 19 weeks. It’s greasy and white, and you might see some of it when you’re born. Along with their growing head hair, babies also have lanugo, a downy layer of hair that covers their entire body.

In this week-by-week pregnancy guide, you’ll learn that:
- Your baby’s skin is beginning to develop pigments that determine his skin tone. He will also be covered in Vernix Caseosa, a thin wax-like substance that helps protect the skin from amniotic fluid.
- The hair on his scalp is growing.
- Your baby’s senses are blossoming. His brain is designating specialized areas for smell, taste, hearing, vision, and touch.
- Research suggests that he may hear your voice now, so keep a check on those swear words. Read, sing, or talk to your baby. Don’t be shy.
- His kidneys continue to make urine.
4 months pregnant belly size
The 19-week pregnant bump varies in size and shape from woman to woman. Women who are expecting their first child may have smaller bumps, however those who have already given birth probably have larger bumps now.
4 months pregnant baby movement
Even though some pregnant women at this stage may clearly feel the baby moving, a lot of this depends on where your 19-week-old baby is located. If the baby is facing inward toward your body, it may be harder to feel any kicks. In other circumstances, they can move so delicately that you might mistake them for gas or a flutter.
But if you’ve already felt your baby move and you think they’ve slowed down or stopped, don’t wait to call your doctor. Even if it’s nothing, it’s better to be safe. Studies show that up to 55% of women who have stillborn babies notice a decrease in the baby’s movements, but they prefer not to inform their doctors in order to avoid upsetting them.

1. Round Ligament Pain
Your belly is growing fast, so the ligaments supporting your expanding uterus cause abdominal aches.
Your uterus is supported by circular ligaments that need to enlarge as it grows. Due to these strained ligaments, your lower abdomen may periodically feel a sharp pain or a dull ache, on one side or other. It most often becomes noticeable when you alter your posture or stand up out of the blue. Call your doctor if it starts to concern you.
2. Dizziness
Pregnancy may cause dizziness because your uterus is growing and putting stress on your blood vessels. In addition, the baby is stuffing your lungs, which reduces your oxygen supply!
3. Leg Cramps
A technique to ease these symptoms is stretching. Stretch your leg, and flex your toes and ankle toward your knees. Try some yoga while you’re pregnant or ask your partner to massage your calves (and back!).
Your little one’s kicks may take you by surprise, though eventually, you will get used to the movements of your little gymnast. Oh, and avoid using your growing bump as a coffee table less the cup, along with its hot content, falls.
Your increased bump size may be causing you heartburn, so here are ways to prevent it.
Additional signs of pregnancy this week could include (as detailed by NHS UK):
- exhaustion and trouble sleeping

- headaches

4 months pregnant ultrasound

Soon you will have a mid-pregnancy ultrasound. You might be having a 19-week ultrasound right now or one may be scheduled for the next weeks. During a 19-week ultrasound, your doctor will look at your baby’s size and shape to check for any anomalies.
Your 19-week ultrasound may be referred to by other people as a “anomaly scan,” “morphology scan,” or “structural scan.”
At your checkup in the second trimester, you’ll also undergo a number of tests. During this visit, routine lab tests such as urine testing, blood sugar tests, physical exams, and others are carried out.
4 months pregnant pregnancy Care
- Keep the aches to a minimum by going on walks and performing simple exercises.
- If you feel light-headed, sit down and do some deep breathing exercises or meditate.
- Speak with your doctor this month to find out if any genetic screening tests are advised for you.
- Take into consideration the potential birthing sites. These might include local hospitals or birthing centers.
- Stay hydrated. Your body is working overtime, so it needs all the fluid it can get. It is simple to become dehydrated during pregnancy, which can cause lethargy, headaches, and dizziness.
- Hip pain may bother you at night. Sleep with a pillow between your knees.
- At four months pregnant, you may not need full-on maternity apparel, but you may want to start looking for more comfortable clothing options so that you’ll be prepared when the time comes.
Exercise for 4 months pregnant woman
Most exercises are fine to do while pregnant as long as you exercise cautiously and don’t overdo them.
The safest and healthiest exercises are swimming, brisk walking, indoor stationary cycling, and low-impact aerobics (taught by a certified aerobics instructor). These activities, which have a low risk of injury and can be performed up to delivery, will be beneficial to your entire body.
Tennis and racquetball are often risk-free activities, but fast movements could be impeded by your shifting equilibrium during pregnancy. Other exercises include running and jogging – in moderation. You might want to choose activities that don’t require much balance or coordination, especially later in pregnancy.
19 weeks pregnant: Your Checklist
- Encourage your spouse to feel your little ninja’s kicks! This is a good way for him to connect with the baby.
- Think about picking out names for your baby. It’s never too early!
