20 Weeks Pregnant: What to Expect and Top Tips for You
Congratulations, you’ve reached the halfway point of your pregnancy! At 20 weeks, your baby is growing steadily, and you’re likely feeling more connected to them than ever. Let’s dive into what this week holds for you and your baby.
Baby at 20 Weeks: A Growing Miracle
Your baby is now about the size of a sweet potato, measuring around 16.5cm from head to bottom and weighing approximately 280g. Here’s what’s happening this week:
- Digestive practice: Your baby is swallowing more amniotic fluid to help develop their digestive system.
- Fully formed limbs: Arms and legs are proportionate, making movements more coordinated.
- Hair and nails: Hair is sprouting on the scalp, and nails are continuing to grow.
- Gender reveal: If you’ve chosen to find out, your anatomy scan may reveal your baby’s gender.
- Sleeping patterns: Baby is settling into regular sleep and wake cycles.
Your little one is growing stronger and more active with every passing day!

Your Body: What to Expect at Week 20
This milestone week often brings noticeable changes and new experiences:
- Stronger movements: You’re likely feeling more distinct kicks, rolls, and stretches now.
- Round ligament pain: As your uterus expands, you might feel occasional aches or sharp pains.
- Weight gain: Steady weight gain is normal as your baby continues to grow.
- Increased appetite: Your growing baby might make you feel hungrier than usual.
- Heartburn: Hormonal changes and a growing uterus can cause acid reflux.
This week is all about celebrating your progress and preparing for what’s ahead.
