Baby Development In Week 16 Of Pregnancy

A major growth spurt is on the way, and in the next three weeks she would be more active and many complicated body systems start functioning. The following listed features are from the book, The Complete Pregnancy Guide for Expectant Mothers by Alex A. Lluch and Dr. Benito Villanueva (2).

Skin: The skin is transparent and pink and shows blood vessels beneath.

Limbs: Her tiny feet can kick and hands make grasping motions. Toenails start growing. She can now suck the thumb.

Eyes: They become increasingly sensitive to light.

Lip: A vertical groove called philtrum or medial cleft begins to appear in the middle of the upper lip, which gives it a distinct Cupid’s bow shape.

Musculoskeletal system: The muscles and bones get organized and the facial muscles move giving way to facial expressions.

Nervous system: It continues to develop, and your baby will have reflexes, thanks to neural control. She will also grab and play with the umbilical cord.

Head and scalp: Head and neck become more erect as the backbone strengthens. The scalp pattern appears though the locks are not visible yet (called patterning of the scalp).

Heart and blood flow: Heart pumps about 25 quarts of blood every day, and this fraction increases as the baby develops.

Placenta: It grows to accommodate several blood vessels, which help in the exchange of oxygen and nutrients.

If you are carrying twins, the development of twin fetuses will be the same as above along with the following symptoms:

  • Your twins’ fingernails grow and unique fingerprints are almost formed.
  • If you spot one of the babies sucking left thumb in an ultrasound scan, chances are he/she may be left-handed.
  • Genitals are formed allowing the sonographer to recognize their gender easily. Girl fetus will have millions of eggs in her ovaries.
  • Their bodies grow faster than the heads. Skin is covered with downy hair, referred to as lanugo, which disappear before birth, but a few babies have it ever after birth.
  • All the limbs and joints move. The skeletal system is soft now, made of rubbery cartilage, and hardens slowly.
  • Chests move up and down and mimic breathing. They take in amniotic fluid in place of air.

16th Week Pregnancy Symptoms and Changes in Your Body:

During the 16th week here is what you might notice:

First kicks: Your baby begins to kick and you can feel the baby move too. These kicks are called flutters or quickening, and can be mistaken for indigestion or stomach rumblings (3).

Bigger breasts: The breasts will grow big by many cup sizes as they are prepping up for nursing.

Pregnancy glow: The increased blood flow during this time makes your face look bright and the active hormones will make your skin oilier and shinier. This is called pregnancy glow.

Backache: The hormonal changes can increase the risk of back pain. You may need some low impact exercises to ease the pain. Also, sit and stand, and stretch your body regularly to alleviate the pain. But before trying anything, check with your doctor.

Constipation: Besides pregnancy hormones making the gastrointestinal tract inactive, the growing uterus puts pressure on the bowels leading to constipation. Have lots of water and take high fibre foods to beat the condition.

Vaginal discharge: This continues to increase, and is good as it protects the vagina from infections. You may be tempted to use douches or wipes but avoid them to prevent genital tract infections and irritations.

Varicose veins: The growing uterus compresses blood vessels causing painful varicose veins. Managing your weight is a must as extra weight gain could increase the load on the circulatory system, leading to varicose veins. Also, do not stand in the same position for a longer time, and keep your feet elevated when sitting.

Bleeding gums: You will notice bleeding gums after brushing as pregnancy hormones cause inflammation, which makes gums susceptible to bleeding, irritation, and bacteria. Good oral hygiene and dentist visits are a must.

Leg cramps: You may suffer from severe leg cramps and pain. Moving and exercising your legs, feet, and ankles can help prevent cramps.

Heartburn: Progesterone helps in expanding your body with the growing baby. It also slows down the movement of food along the digestive system and causes heartburn. Take smaller meals at frequent intervals rather than larger meals three times a day. Avoid eating spicy foods and lying down soon after the meals.

Nosebleeds: It may seem alarming, but nosebleeds during the 16th week are due to the additional blood flow in the body, which ruptures the tiny blood vessels of the nose. Use a humidifier or a neti pot to moisten your dry nose.

Forgetfulness: You may become a little forgetful or face trouble concentrating. Though the actual reason is not known, “PregnancyBrain” could be biological or a result of the endless thoughts on your mind.

Dry and itchy eyes: Another effect of pregnancy hormones, dry and itchy eyes can be treated with over-the-counter eye drops only after consulting your healthcare provider.

If you happen to find any other symptoms during the 16th week, you should let your doctor know about them.

How Is Your Growing Belly?

You may be a pound heavier thanks to the extra poundage of blood and fluid volume. At this stage, your uterus holds almost a cup of amniotic fluid.

Your Second OB/GYN Visit:

You will have your second prenatal appointment around this time.

Medical history: Your doctor will check your general health and take details of any symptoms you may experience. You must tell the doctor of any issues or queries you have.

Physical examination: Your blood pressure, weight, and height are measured. Physical examination also includes checking thyroid, breasts, lungs, and heart. The doctor may examine the vagina, uterus, ovaries, and cervix.

Lab tests: Your doctor will check for signs of gestational diabetes, preeclampsia, or any urinary tract infections through urine tests. There would also be a 16-week ultrasound to lessen the chances of miscarriage.

Doppler ultrasound test: Your ob-gyn will use a handheld device called Doppler to make you and your partner hear the baby’s heartbeat for the first time, which will become a routine hereafter.

Tests and procedures: You may have to undergo a few procedures for detecting congenital disabilities or genetic disorders and abnormalities.

  • Multiple marker screening: It is a blood test that detects Down syndrome. It uses certain markers which provide information on congenital disabilities such as spina bifida. This test is also done in combination with a special ultrasound scan known as nuchal translucency screening to better assess any abnormality risks.
  • Amniocentesis: It diagnoses Down syndrome and chromosomal abnormalities, neural tube defects, and genetic disorders. However, this holds a small risk of miscarriage. Therefore only those who are known to be at greater risk of genetic or chromosomal abnormalities should go for it.
  • Alpha-fetoprotein (AFP) tests: AFP blood test checks for any neural tube defects.

Gender Scan On Ultrasound:

A boy ultrasound looks like a snail or turtle.

A girl ultrasound has three distinct lines (outline of vulva – the external part of the female genitalia). But a better visual can only be obtained when the fetus reaches 20 weeks as gender differences are definite then.

9 Tips For A Better 16th Week Pregnancy:

With the morning sickness gone, this is a good time to focus on healthy eating and remaining fit.

  1. Eat right: If you are craving for sweet foods, you can have yogurt or fruit instead of candies. If you want to have salty foods, snack on string cheese. They not only satisfy your cravings but also fulfill calcium and protein needs.
  1. Exercise: A half-hour workout is a good idea. Walking and swimming are better options for low-intensity activities, but do discuss with your doctor before trying any exercise.
  1. Research: Start looking out for cribs, strollers, baby car seats, and other baby items. Baby shopping could be difficult once the little one is born.
  1. Sleeping on side: This becomes more important from this week and sleeping on the back is not recommended. You could use pillows for support while sleeping on your side or buy maternity pillows designed specially for pregnancy.

  1. Decisions matter: Be firm on any decisions you take, whether they pertain to your health, finances, or the baby.
  1. Fun with the bump: Now that the bump is showing, you can take pictures and even make stop animation movies. You could stand in the same place and position every day and take pictures to create your own little movie.

Nutrition In 16th Week Of Pregnancy:

According to the American Centre for Disease Control (CDC), you need to have an extra of 340 calories every day from your second trimester. However, it depends on your weight and the level of activity.

  • Take whole grains, low-fat dairy products, vegetables, and lean meat. Avoid processed foods, sugar-loaded desserts, and packaged snacks.
  • Keep filling and healthy snacks such as hummus, plain yogurt, nut butter, baby carrots, some raw veggies, and fresh fruits such as apples, pomegranates, bananas, handy. This way, you are less likely to eat junk.
  • Replace fatty foods with non-fat frozen yogurt, bagel or air-popped popcorn instead of ice cream, doughnuts, or potato chips.
  • Drink water rather than a glass of juice or beverages.

If you are underweight, normal, or facing difficulty in putting on weight, then try the following nutritional tips:

  • Have a milkshake every day for the calorie boost.
  • Include healthy fats such as nuts and avocados in your diet.
  • Eat dry fruits rather than fresh fruits as they are filling and healthy.

Frequently Asked Questions:

1. How much weight should you gain in the 16th week of pregnancy?

If you were at a healthy weight when you started your pregnancy, try to gain around 12 to 14 pounds in this trimester (that is towards a total of 25 to 35 pounds for your entire pregnancy). If you were underweight, overweight, or carrying twins or more, your doctor may advise you to gain a little more or less.

2. How can you keep your weight gain on track?

According to American CDC that issues pregnancy weight gain guidelines, you should eat about 340 calories every day in your second trimester. However, the caloric requirement depends on your weight and activity level.

3. How many months is 16 weeks?

16 weeks is four months or the end of four months of pregnancy.

4. If I am 16 weeks pregnant, when is my due date?

Your due date is usually calculated by adding 40 weeks (i.e., 280 days) to the first day of your last period (if you assume a 28-day menstrual cycle). So, if you are 16 weeks pregnant now, you will be delivering your baby about 24 weeks later. If you deliver on the expected due date, your baby will be 38 weeks, not 40 since your last menstrual period and ovulation are taken as first two weeks of your pregnancy.

Hope you will follow the tips and take care of yourself. Remember the more you take care, the safer will your pregnancy be. If you have anything to share, feel free to write in the comment section.
