Second trimester

17 Weeks Pregnant

Mid-pregnancy approaching

This week your baby is around the size of a pear.

How your baby is developing

  • Movement and reflexes are developing.
  • Your baby keeps growing steadily this week.

What may be happening in your body

  • Round ligament aches, brief pulls low in the abdomen, can come and go as the womb keeps growing.
  • Your waist will start to vanish as your womb moves up and out of your pelvis — you may look more obviously pregnant now.
  • You might start to feel your baby move now, though many parents first notice movements between 18 and 24 weeks.

How you may be feeling

  • Picturing the baby more clearly can stir excitement and worry at the same time for some.
  • As a mid-pregnancy scan approaches, some feel a renewed flutter of anticipation or nerves.
  • Daydreaming about meeting your baby is common, and so is the odd anxious thought alongside it.

Worth remembering

Mixed feelings as it becomes more real are a normal part of this stage.

A closer look

Aches as your bump grows

The ligaments supporting your growing womb soften and stretch, which can strain your lower back and pelvis and cause brief pulling aches. Your waist also starts to disappear as the womb moves up out of the pelvis, so your shape can change quite quickly now. Resting when you can, and flat supportive shoes, help many people with the aches.

Movement may be close for some

Your baby is moving and developing reflexes, though most people do not feel it yet at 17 weeks. First flutters are usually noticed between 16 and 24 weeks, and often later with a first baby. So not feeling movement now is exactly what to expect at this stage.

Something you can do this week

Gentle planning, only if you feel like it, can be reassuring.

What comes next

The halfway mark is close, and many parents first notice movement in the coming weeks.
