What to expect this week

At 23 weeks, your baby is about the size of a grapefruit and is becoming more active every day. You might start noticing rhythmic little jerks, those are hiccups! It’s a strange but reassuring sensation.

Your baby’s hearing is developing, and they can now pick up sounds from the outside world. Talking, singing, or even playing music can be soothing for them. Their lungs are also maturing, preparing for their first breath.

You might feel Braxton Hicks contractions this week. These practice contractions are usually painless and irregular, but they can feel like a tightening across your belly. It’s your body’s way of preparing for labor.

Your growing belly might start causing some discomfort, like lower back pain or swollen feet. Elevating your feet and practicing gentle stretches can help.

  • Hiccups. Rhythmic little jerks you might feel.
  • Hearing. Your baby can now hear sounds.
  • Braxton Hicks. Practice contractions that are usually harmless.
  • Discomfort. Back pain and swelling are common.

Things to be aware of

Braxton Hicks contractions are normal, but if they become regular, painful, or more frequent, it’s worth mentioning to your provider. Sometimes they can be a sign of preterm labor.

Swelling in your feet and ankles is common, but sudden or severe swelling, especially with headaches or vision changes, could be a sign of preeclampsia. Keep an eye out for these symptoms.

If you notice unusual discharge, like a gush of fluid or spotting, it’s important to contact your provider. It could indicate your water breaking or another issue that needs attention.

What might happen this week

You’re nearing the viability milestone, the point when your baby has a chance of surviving outside the womb with medical help. While every day in utero is best, this is a reassuring step.

If you haven’t already, your provider might suggest scheduling your glucose screening test soon. This test checks for gestational diabetes and is usually done between weeks 24 and 28.

You might also start discussing your birth plan with your provider. Whether you’re planning a hospital birth, home birth, or something in between, it’s a good time to think about your preferences.

  • Ask about the glucose screening test
  • Start brainstorming your birth plan
  • Monitor for signs of preterm labor
