Baby is now the size of a large ear of corn
Welcome to Week 24. This week is an important milestone in pregnancy. Your baby continues growing rapidly and major organs are becoming more developed every day. Many mothers are now feeling strong, regular movements throughout the day — kicks may become powerful enough to startle you, and you may begin noticing your baby's daily routines. As the third trimester approaches, pregnancy often starts feeling more physical but also more rewarding.

Is shortness of breath normal?
