Welcome to Week 19. You are nearly halfway through your pregnancy, and your baby is growing rapidly. Movements are becoming stronger, body proportions are becoming more balanced, and important sensory systems continue developing. Baby kicks may become more noticeable, the anatomy scan may be taking place around this time, and the reality of meeting your baby can start feeling much more tangible.

Frequently asked questions

Are stronger movements normal?

Yes. Many mothers notice a significant increase in movement around this time as muscles become stronger.

What if I haven't felt movement yet?

That can still be completely normal, especially for first-time mothers or those with an anterior placenta.

Why does my back hurt?

Your growing uterus and changing posture place additional strain on your back and supporting muscles.

Is it normal to feel hungrier?

Yes. As your baby grows, your body's energy requirements increase.
