At 13 weeks, your body has begun to adjust to being pregnant, and many of the early discomforts are likely fading away. With renewed energy, you’re stepping into the second trimester—a period often considered the most enjoyable part of pregnancy. Your baby has now grown to about 7 centimeters in length and weighs approximately 30 grams.

At 14 weeks, your baby has grown to about 8 centimeters in length and weighs around 60 grams. Although you may not feel it yet, your baby is becoming increasingly active, moving their tiny arms and legs. As the amount of amniotic fluid increases, your baby has plenty of room to stretch and explore. Excitingly, your obstetrician might even be able to predict your baby’s sex!

At week 15, your baby’s body is still covered with a fine layer of soft hair called lanugo, which helps hold in the protective coating that shields their delicate skin from the amniotic fluid. At this stage, your baby may occasionally swallow a small amount of amniotic fluid, and when the stomach is full, they may hiccup. The placenta works continuously to filter and refresh the amniotic fluid, keeping your baby’s environment clean and nourishing.

At 16 weeks, your pregnancy continues to progress, bringing with it exciting changes for both you and your baby. The hCG hormone is gradually replaced by progesterone, which can leave you feeling more fatigued. Your baby is now about 15 centimeters long and weighs around 130 grams—roughly the size of an avocado. Although your baby’s eyes remain closed, they can now begin to differentiate between light and dark. Let’s explore what else is happening during this stage of your pregnancy.

Around this time, many expectant mothers start to feel the first signs of life inside their belly, a truly magical experience! Don’t worry if you haven’t felt anything yet; this is completely normal, and you’ll have that special moment when the time is right. Your baby is now about 18 cm long and weighs around 190 grams — roughly the size of a pear. In addition to moving their arms and legs, your baby can now move their head, lips, hands, feet, and even individual fingers and toes.

Starting this week, your baby’s brain begins developing rapidly—about 90 grams each month. The head now makes up one-third of the total body length. Measuring around 20 cm and weighing about 220 grams, your baby is roughly the size of a bell pepper. Let’s take a closer look at what’s happening during this stage.

Congratulations! You’re almost halfway through your pregnancy journey. At this stage, your baby measures about 22 cm long and weighs around 250 grams—roughly the size of a large mango. Since the connective tissue under the skin hasn’t fully developed, your baby’s skin may look a bit wrinkled. As the senses grow stronger, your little one may begin to hear external sounds like your voice or singing, though the heartbeat and rhythms of your body remain the most familiar soundtrack.

Congratulations—you’ve reached the halfway point of your pregnancy! At this stage, your baby measures about 24 cm and weighs around 300 grams, moving frequently throughout the day. This is also when many expectant mothers undergo the 20-week ultrasound, an important scan to check the baby’s growth and detect any visible abnormalities. If the baby cooperates, you may even find out the gender during this appointment.
