Your pregnancy week by week:
Weeks 17 – 20:
Congratulations on your fifth month of pregnancy. Your baby belly will be pretty visible, so you will feel more pregnant than before. Below we have explained to you the weeks of the fifth month of pregnancy, so you should not be worried about which changes will you experience.
- Baby: In the last two weeks, your baby has doubled in its weight. Also, the fat begins to form, which can help your baby’s heat production and metabolism. His or her lungs are beginning to exhale amniotic fluid and the circulatory and urinary systems are working. The eyelashes, eyebrows, and hair on the head are filling in. In this week, your baby weighs about 150 grams and he or she is still growing quickly. Your baby’s body will increase in size and it will become in proportion with the size of his or her head. His or her face will start to look like a real human.
- Mom–to–be: In this week, you are showing more than before. Usually, women gain weight from five to ten pounds. Also, you can notice that your appetite is growing. As your baby is growing, your skin is stretching thinner and it can be more sensitive, so you need to resist the urge to scratch. You should find a soothing cream that can ease the itch.
- Tip of the week: You need to change positions slowly, especially when you move from a lying down position to sitting or from a sitting position to standing because in this way you will avoid feeling dizzy or faint. If you feel lightheaded, then you need to sit down and lower your head or lie down for a moment.
- Baby: The rapid growth spurt of your baby is tapering off, but the reflexes are kicking in. Your baby can stretch, yawn and make facial expressions, even frown. Also, his or her taste buds are beginning to develop and they can distinguish sweet from bitter. Your baby can suck its lips if they are stroked and it can swallow and even get hiccups. Your baby’s retinas become sensitive to light and if bright light is shined on your abdomen, then your baby will probably move to shield its eyes.
- Mom–to–be: In this week, your uterus is about the size of a cantaloupe and it can be probably felt just below your navel. The mid-pregnancy ultrasound can be performed between 18 and 22 weeks to see the baby’s growth and development and to verify the due date. The ultrasound may show whether your baby is a boy or girl, which depends on the position of your baby. In this period, your heart needs to work 40 – 50% harder to support your pregnancy.
- Tip of the week: You can ask your partner to go with you to the ultrasound. This is a chance to catch the first glimpse of your baby together.
- Baby: In this week, the skin of your baby is developing and it is transparent. It appears red because the blood vessels are visible through it. Also, the creamy-white protective coating (known as vernix) begins to develop on your baby’s skin.
- Mom–to–be: As your baby continues to grow, you can feel some mid-pregnancy aches and pains by now, such as backache, mild swelling of ankles and feet, leg cramps, constipation, heartburn, dizziness, and lower abdominal aches. Also, dilated blood vessels can cause tiny and temporary red marks (they are known as spider nevi) on your arms, shoulders, and face.
- Tip of the week: You need to take care of yourself. You should try to not get overtired while your baby is growing so quickly.
- Baby: From this week, your baby can hear sounds, such as your voice, heart, and your stomach growling, as well as sounds outside your body. If the sound made near you is loud, then your baby will cover its ears with its hands and it may even become startled and jump. Your baby is moving often. He or she is kicking, punching, wiggling, and turning. In this week, your baby weighs around 400 grams and measures about 25 cm in length. Your baby’s muscles are developing rapidly and there is a lot of space and fluid in the amniotic cavity for your baby to move around.
- Mom–to–be: In week 20 you are in the midpoint of your pregnancy. The uterus is just about even with your navel and your waistline has pretty much disappeared. Bladder infections are more likely to happen because some muscles in the urinary tract relax. You can notice that your breathing will deepen and you may sweat more than usual. This is happening due to your thyroid gland is more active.
- Tip of the week: This week is the halfway point during pregnancy. If you have backache, then you should watch your posture. You should sit with a footstool or use an ergonomic chair. You should avoid standing for too long, sleep with a small pillow under your side at the waist, and lift things with your legs instead of your back.
What is happening inside you:
The hair is beginning to grow on your baby’s head. The lanugo, which is soft fine hair, covers his or her shoulders, back, and temples. This hair is protecting your baby and it is usually shed at the end of the baby’s first week of life. The whitish coating, called vernix caseosa, is covering your baby’s skin. This cheesy substance is shed just before birth. It is thought that is protecting your baby’s skin from long exposure to the amniotic fluid. Also, you can begin to feel your baby’s moves, because he or she is developing muscles and it is exercising them. This movement is known as quickening.
