Week 18
Reviewed by Dr. Humaira Latif, OB-GYN & Ultrasound Specialist
Welcome to week 18 of your pregnancy. Here’s a gentle look at what to expect at 18 weeks pregnant — baby’s size, changes in your body, common 18 weeks pregnant symptoms and a caring tip from Dr. Humaira.
Baby's size
The size of a bell pepper — about 14.2cm.
What's happening
Baby's ears are now in their final position, and hearing is developing — baby may start responding to loud sounds. If you're having a detailed anatomy scan, this is often around when it's scheduled (weeks 18–22).
Your body
Most women are noticeably showing by now. You may feel more consistent baby movement.
Common symptoms
- More noticeable movement
- Backache
- Mild swelling in feet/ankles by end of day
- Vivid dreams (common, harmless)
- Sudden or severe swelling of face/hands
- Severe headache with vision changes
- Reduced fetal movement once you've established a regular pattern
Talking or playing music near your belly from now on is a lovely bonding habit — baby's hearing is developing and can start recognizing familiar sounds.
