Congratulations on coming this far. Now you're 20 weeks pregnant—halfway there! So, how are you feeling, Mommy? It’s an exciting milestone—your baby is growing rapidly, your body is changing in extraordinary ways, and your bond with your little one is getting stronger day by day. Feel giddy with excitement? We’re sure you must be curious to know all about your little one inside, the growth, and something new about them. Well, this guide is just about this.
Let’s explore what to expect in week 20 of pregnancy– from fetal development, common symptoms to helpful tips that keep you feeling your best during this special journey.
Just like last week, your baby is busy developing vital organs and systems to show more activity. They might be kicking, punching, or even sucking their thumb. This thumb-sucking helps them practice sucking, which they'll need to do when feeding after birth. Additionally, they’re producing meconium (baby’s first poop). At 20 weeks pregnant, it’s more or less the same as week 19, just a few things to add on to their tiny existence. If you don’t know, your baby’s skin has a covering, known as vernix caseosa. It protects their skin from irritation after being in amniotic fluid for so long. This white substance also helps during labour to pass through the birth canal.
Moreover, their ears are not fully developed, yet they can hear sounds from outside your uterus. Seems like a miracle!
Around now, your baby is producing antibodies that will protect them from getting sick. The two types of antibodies that your baby is producing are called immunoglobulin G (IgG) and immunoglobulin M (IgM). This might sound science-heavy, but IgG and IgM have pretty simple jobs. IgG is responsible for fighting infections caused by bacteria and viruses, while IgMs are the first antibody that your body produces after being exposed to new germs. Clever, right?
Your baby is about 6.3 inches (16 cm) long from crown to rump and weighs around 11 ounces (312 grams). That’s roughly the size of a banana or a small cantaloupe!
You are 5 months pregnant (18 weeks after gestation) at 20 weeks. Isn’t it amazing, Mommy? Well done for your good work. You have reached this far. It means you’re taking good care of yourself, and your baby is happy and healthy inside.
Your baby is now fully formed, with visible eyebrows, eyelashes, and hair beginning to grow. Nails have grown towards the ends of the fingers. The skin is thickening and creating multiple layers. They are on a roll— taking up more space inside the uterus, so be prepared, mama bear. You may start feeling a little stiff there! Because their continued growth may put pressure on your organs, such as the lungs, stomach, bladder, and kidneys.
Now that you know the baby has taken the full shape and form, you must be eager to watch them, right? The mid-pregnancy anatomy scan, typically done around 20 weeks, is a detailed ultrasound. It examines your baby’s growth and development. E.g. the size and position, structural abnormalities of bones (if any), visible organs. The technician and doctor will examine the following details:
This scan provides important reassurance and helps detect any potential issues early on.
While some early pregnancy symptoms may have eased, new ones might take their place. Here are some common symptoms during this period:
When you are 20 weeks pregnant, your baby bump is more noticeable, and you may need to switch to maternity clothes if you haven’t already. Your uterus is at about the level of your belly button, and you may notice some linea nigra (a dark vertical line) forming on your abdomen.
Yes! This is the time many women feel their baby’s first movements, known as “quickening.” It may feel like flutters, gas bubbles, or light tapping. If you haven’t felt anything yet, don’t worry—it’s more common to feel movements later in a first pregnancy. However, at 20 weeks pregnant, an expectant mother can feel her baby’s movements internally, and the healthcare provider can visualise them externally through the abdomen.
Congratulations — if you’re 20 weeks pregnant, you’ve officially reached the halfway point of your pregnancy journey! Whether you’re marvelling at your growing bump, planning the nursery, or still trying to figure out if that was a baby kick or just gas (hey, no judgment!), this is a moment worth celebrating.

Around 20 weeks of pregnancy, babies in the womb start to show more noticeable patterns of sleeping and waking. In one study, doctors used ultrasound to watch the behaviour of babies between 20 and 40 weeks of pregnancy. They looked closely at two types of sleep: REM (Rapid Eye Movement) sleep and non-REM sleep. They found that as the baby grew, the amount of REM sleep increased, which is a sign that the baby’s brain and nervous system are developing well.
Apply moisturising creams, wear loose clothes, stay hydrated and avoid hot showers. If itching becomes severe, consult your doctor right away.
It’s a fun pregnancy myth with some truth! One study found a correlation between higher estrogen levels (linked to heartburn) and babies born with more hair. But not everyone with heartburn has a hairy baby.
Sleeping on your left side improves blood flow to the placenta and kidneys. It also helps reduce pressure on the inferior vena cava, a major vein that carries blood to your heart.
