You're lying on the sofa in the evening, gently stroking your baby bump – and suddenly it feels rock hard. Everything tightens for a few seconds, then your uterus relaxes again. Was that a contraction? This uncertainty is completely normal. But don’t worry: your body is simply showing you that it’s already hard at work training for the big day.

What Happens in Week 20 of Pregnancy?

You’ve reached the halfway point of your pregnancy – a magical milestone! Your baby is now about the size of a small banana and weighs around 300 grams. You might even feel the first gentle kicks, known as fetal movements. But it’s not only your baby growing rapidly – your body is already preparing for labor.

Practice contractions can begin as early as week 20. These so-called Braxton-Hicks contractions are completely normal and signal that your uterine muscles are training. They prepare your body for the upcoming birth and help the baby move deeper into the pelvis – although this happens much later, near the end of pregnancy.

What Do Practice Contractions Feel Like?

Practice contractions typically are:

  • Irregular and sporadic
  • Relatively short (lasting 10-30 seconds)
  • Painless or only mildly uncomfortable
  • Felt as a tightening of the belly that then relaxes
  • Do not increase in intensity over time

Many women describe the sensation as a tightening or pulling, as if the belly briefly hardens. Some barely notice them, while others find them surprisingly strong – both experiences are perfectly normal.

Practice Contractions vs. Real Labor: How to Tell the Difference

The big question many expectant moms ask is: How do I know when it’s really happening? Especially with your first child, this uncertainty can be overwhelming. But there are clear signs to help you distinguish between the two.

Signs of Real Labor Contractions

True labor contractions typically have these characteristics:

  • Regularity: They come closer together over time (starting about every 10 minutes, then every 5-7 minutes)
  • Duration: Each contraction lasts 20-60 seconds and gets longer
  • Intensity: They steadily grow stronger and more painful
  • Pain: Often begins in the back and moves in waves toward the front
  • Persistence: Do not ease with position changes or warm baths

As a general rule, contractions about ten minutes apart are the first signs of labor. But at week 20, it’s far too early for that!

The Bathtub Test

A simple and reliable method to distinguish contractions is: practice contractions stop when you take a warm bath or shower, but real contractions continue and may even increase with warmth. This test can quickly give you clarity and help you stay calm.

Preterm Labor: When You Should Pay Attention

While practice contractions are completely normal, some signs you shouldn’t ignore include: a hard belly occurring more than three times per hour, along with back and lower back pain — these may indicate preterm labor and should be medically evaluated.

Warning Signs of Preterm Labor

  • More than three contractions per hour or more than ten per day
  • Lower back or lumbar pain
  • A feeling of pressure in the pelvis
  • Cramping pains in the lower abdomen
  • Vaginal bleeding or fluid leakage
  • Changes in vaginal discharge (watery, mucous-like, or bloody)

If you notice any of these signs, contact your doctor or midwife right away. It’s always better to check once too often than too little — they’re there to support you and take your concerns seriously.

Other Signs Your Body Is Preparing

Besides practice contractions, there are other physical changes that show your body is slowly gearing up for birth – even if it’s still months away. These symptoms are especially common in the last weeks before birth but can occasionally appear earlier.

Typical Accompanying Symptoms

  • Increased Urge to Urinate: Your baby is pressing more on your bladder
  • Back Pain: Your growing uterus shifts your center of gravity
  • Restlessness and Insomnia: Hormones and changing body awareness
  • Occasional Nausea: Hormonal fluctuations can return
  • Changes in Bowel Movements: Your digestive system reacts to hormonal changes

All these signs are part of your body’s natural preparation, showing that everything is progressing – even if some symptoms feel uncomfortable at times.

How to Support Your Body Now

Week 20 is a wonderful time to start consciously preparing for birth. You don’t need to panic or train intensively — it’s about building a loving connection to your body and trusting it.

Practical Tips for the Coming Weeks

  • Breathing Exercises: Begin simple breathing techniques that will help you during labor
  • Gentle Movement: Yoga, swimming, or walks keep you fit and flexible
  • Relaxation Rituals: Find what soothes you – warm baths, meditation, music
  • Pelvic Floor Training: Strengthens muscles for birth and postpartum recovery
  • Childbirth Preparation Classes: Now is an ideal time to sign up
  • Talk with Your Midwife: Build a trusting relationship

Most importantly: Listen to your body. If it asks for rest, give that to yourself. If you have energy, use it. There’s no right or wrong – only what feels right for you.

Common Questions About Contractions at 20 Weeks

Are Practice Contractions Harmful to My Baby?

No, practice contractions are completely harmless. They only train your uterine muscles and prepare your body. Your baby is safe in the amniotic sac and doesn’t notice them.

How Often Are Practice Contractions Normal?

Occasional practice contractions a few times a day are perfectly normal. However, if you notice more than three contractions per hour or more than ten per day, you should have this checked by a healthcare professional.

Can I Prevent Practice Contractions?

You cannot prevent practice contractions – and that’s a good thing! They are a natural part of pregnancy. You can reduce them by drinking plenty of fluids, avoiding stress, and resting regularly.

When Should I Go to the Hospital?

At 20 weeks, this is not a concern. Near the end of pregnancy, the 5-1-1 rule applies: contractions every 5 minutes, lasting at least 1 minute each, lasting over an hour. Then it’s time to go. For preterm labor, bleeding, or rupture of membranes, contact your doctor immediately!

What Is the Mucus Plug and When Does It Come Out?

The release of the slightly bloody mucus plug (also called "show") is a clear sign that labor is approaching. It seals the cervix during pregnancy. At 20 weeks, this is not relevant yet – the mucus plug usually comes out shortly before or during labor.

Trust Your Body – It Knows What to Do

Week 20 of pregnancy marks a special moment: you’re halfway there, and your body is already starting to prepare for the grand finale. The first practice contractions might surprise or unsettle you – but they are a beautiful sign that everything is on track.

Take time to get to know your body. Observe the signals it sends without panic. Build a loving connection with yourself and your baby. And above all: trust that your body knows exactly what it’s doing. It follows an ancient, wise plan – and you can rely on that.

The weeks and months ahead are a time of growth, learning, and preparation. Enjoy them as best you can. And if doubts arise: your midwife, doctor, and other mothers are here for you. You are not alone on this journey.
