Your Baby’s Development at 16 Weeks
Let’s start by learning all about your baby’s development during this time. At 16 weeks of pregnancy, you can expect a major growth spurt in your baby, and in the next three weeks, you can expect them to be more active, and many of their complicated body systems will start to function.
How Big is Your Baby at 16 Weeks?
At 16 weeks of pregnancy, your baby will be the size of an avocado and could fit in the palm of your hand. They will measure about 4.6 inches (11.6 cms), and weigh 3.5 ounces (100 gms). You can follow the pregnancy week-by-week posts to get more idea about your baby’s development every week and common symptoms that you can expect to notice.
Foetal Development at 16 Week Pregnancy
According to doctors, you can expect the following milestones in your baby’s growth and development:
Skin: During this time, the skin is transparent and pink, and shows blood vessels beneath.
Limbs: Your baby’s tiny feet can kick now and their hands can make grasping motions. Their toenails start to grow as well, and they can now suck their thumb.
Eyes: At 16 weeks pregnant, your baby becomes increasingly sensitive to light.
Lip: The philtrum or the medial cleft begins to appear in the middle of your baby’s upper lip, which gives it a distinct Cupid’s bow shape.
Nervous system: Their nervous system continues to develop, and your baby will also have reflexes during this time, thanks to neural control. They will also grab and play with the umbilical cord.
Musculoskeletal system: Their muscles and bones get organised, and their facial muscles start moving, giving way to facial expressions.
Head and scalp: As their backbone strengthens, your baby’s head and neck will become more erect. Also, their scalp patterning will appear, although the locks won’t be visible yet.
Heart and blood flow: Your baby’s heart will pump about 25 quarts of blood every day, and this fraction will increase as they continue to develop.
Placenta: The placenta will grow to accommodate several blood vessels, which will further help in the exchange of oxygen and nutrients.
If you are carrying twins, their development will be the same as above, along with the following symptoms:
Your twins’ fingernails grow and they go on to form unique fingerprints.
If you spot one of your babies sucking their left thumb in ultrasound, then chances are they may be left-handed.
Your twins’ bodies will grow faster than their heads, and their skin will be covered with downy hair, referred to as lanugo, which usually disappears before birth.
All of their limbs and joints will begin to move, and their chests move up and down to mimic breathing.
Common Symptoms That You’ll Experience This Week
At 16 weeks of pregnancy, your body will undergo several changes. You will also experience common symptoms and will notice that some of them are similar to early signs of pregnancy. You will notice:
Bigger breasts: Your breasts will continue to grow to prep up for nursing.
Backache: The hormonal changes during pregnancy, increase the risk of back pain. You can try some low-impact exercises to ease the pain. Also, sit, stand, and stretch regularly to alleviate the pain.
Constipation: During this time, your pregnancy hormones can make your gastrointestinal tract inactive. Also, the growing uterus may put pressure on your bowels, leading to constipation. Drink lots of water and consume high-fibre foods to beat this concern.
Vaginal discharge: You will also notice an increase in vaginal discharge during this time, but don’t fret, as it helps keep your vagina protected from infections and bacteria. However, if you notice a foul smell, consult your doctor immediately.
Bleeding gums: Pregnancy hormones cause inflammation in your body, which makes your gums susceptible to bleeding. Maintain good oral hygiene during this time, and visit your dentist regularly for checkups.
Varicose veins: The growing uterus compresses blood vessels in your body, causing painful varicose veins. Plus, additional weight gain during this time can also deteriorate this condition. Hence, focus on maintaining a healthy weight and avoid standing in the same position for a long time.
Forgetfulness: During this time, you may become a little forgetful and even have trouble concentrating. While the exact reason for this condition, more commonly known as pregnancy brain is unknown, it is often associated with the result of endless thoughts on your mind.
Heartburn: The increase in progesterone in your body slows down the movement of food along the digestive system, causing heartburn. To avoid this condition, you can have smaller meals at frequent intervals, and avoid eating spicy and oily foods.
Your Body at The 16th Week of Pregnancy
When you were in your first trimester, you could easily hide your pregnancy by wearing flowy clothes. But when you are 16 weeks pregnant, your uterus will begin to grow rapidly, and you may not be able to hide your pregnancy anymore, even if you wanted to.
You are also likely to experience your baby’s first kicks during this time and will be able to feel them move too. These kicks are called quickenings or flutters and can be mistaken for stomach rumblings or indigestion.
Additionally, you will experience a pregnancy glow, due to increased blood flow during this time, making your face look brighter than usual. The active hormones in your body will also make your skin oilier and shinier.
16 Weeks Pregnant Belly
At 16 weeks, your baby bump will be visible, and your weight gain will be considerable too. However, keep in mind that how your pregnant belly looks at 16 weeks may differ from one person to another. So, before panicking, visit your doctor for more information and confirm that your baby is going at a healthy rate without any complications.
You can also use a pregnancy month calculator to track your progress and determine if your baby is growing at the right rate or not.
Do You Need An Ultrasound at The 16th Week of Pregnancy?
When you are 16 weeks pregnant, you will have a four-month prenatal visit. Your doctor will conduct a thorough physical examination and also suggest some lab tests to check for signs of preeclampsia, gestational diabetes, and urinary tract infections.
The doctor will also conduct a doppler ultrasound test during this appointment. Your ob-gyn will use a hand-held device called Doppler to make you and your partner hear your baby’s heartbeat for the first time, which will become a routine hereafter.
