Week 17
Reviewed by Dr. Humaira Latif, OB-GYN & Ultrasound Specialist
Welcome to week 17 of your pregnancy. Here’s a gentle look at what to expect at 17 weeks pregnant — baby’s size, changes in your body, common 17 weeks pregnant symptoms and a caring tip from Dr. Humaira.
Baby's size
The size of a turnip / pear — about 13cm.
What's happening
Baby's skeleton is hardening from cartilage into bone. Fat stores are beginning to develop under the skin, and the umbilical cord is thickening and strengthening.
Your body
Your ligaments are stretching to support your growing uterus, which can cause sharp, brief 'round ligament pain' on one or both sides.
Common symptoms
- Round ligament pain
- Backache
- Stuffy nose
- Increasing appetite
- Round ligament pain is normally brief and sharp — pain that is severe, constant, or with fever needs prompt medical review
Round ligament pain is very common and usually harmless — it tends to happen with sudden movement (standing up fast, coughing). Moving slowly and supporting your belly when you shift position helps.
