Week 20 · Second Trimester

Your baby is the size of a Banana

📏 16.4 cm⚖ 300g

At 20 weeks pregnant you're in the second trimester. This week covers the halfway milestone, the 20-week anomaly scan checklist, and gender reveal.

This week

Halfway there! Baby has fingerprints and taste buds.

💡 Tip for mom

Time for the mid-pregnancy anatomy scan.

You are officially halfway there. Week 20 is a landmark — the anomaly scan checks every major organ, tiny fingerprints are complete, and your baby is now the length of a banana. Kicks should be a daily event by the end of this week.

Common symptoms at 20 weeks pregnant

  • A clearly rounded, firm bump
  • Stronger, more rhythmic kicks
  • Occasional shortness of breath as the uterus pushes upward
  • Stretch marks appearing on the belly, hips, or breasts
  • Faster hair and nail growth

Tips for week 20

  1. Bring your partner or a loved one to the anomaly scan — it is often the most emotional visit of the pregnancy.
  2. Start moisturising the belly twice a day. It will not prevent stretch marks (they are genetic) but soothes the itch.
  3. Sleep on your left side with a pregnancy pillow supporting the belly and knees.
  4. Begin thinking about childbirth-education classes — most run six weeks and are best started around week 28.

This week's checklist

  • Attend the 20-week anomaly scan
  • Choose a birth-education class
  • Start a stretch-mark care routine

Frequently asked questions

What if the 20-week scan finds something?

Most findings are minor and resolve. If further review is needed, you will be referred to a maternal-fetal-medicine specialist within days for a detailed second look.

How many kicks should I feel at 20 weeks?

Kick counts do not become a formal check until around 26-28 weeks. For now, notice a general pattern — some quiet mornings and lively afternoons are normal.

Can I still exercise vigorously?

Yes. Continue the exercise you were doing before pregnancy, avoiding any activity with fall risk or belly contact. Stop if you feel dizzy, breathless beyond talking pace, or contract painfully.

When to call your provider

Most weeks of pregnancy pass without alarm, but a small set of symptoms always deserves urgent attention. Call your doctor or head to the nearest maternity emergency room straight away for any of the following:

  • Heavy, bright-red vaginal bleeding or the passage of clots
  • Severe headache with visual changes, upper-abdominal pain, or sudden facial swelling
  • Any leaking of fluid before 37 weeks or a sudden gush of fluid at any week
  • Severe one-sided lower-abdominal or shoulder-tip pain (possible ectopic in early pregnancy)
  • Fever above 38 °C, painful urination, or one-sided calf swelling

Where week 20 sits in the second trimester

The second trimester covers weeks 13 to 27 and is often called the honeymoon of pregnancy. Energy comes back, morning sickness fades, and this is the phase when you feel the first kicks, complete the anatomy scan, and start planning practical things — nursery, maternity clothes, and childbirth classes. Week 20 sits comfortably in this window.
