Week 26
Fetal Development:
Your baby could weigh about two pounds now and be around 9 inches long (crown of the head to the rump). As the blood vessels in the lungs began last week, the air sacs in the lungs begin this week. The lungs begin to secrete surfactant which covers the inner lining of the air sacs which then allows the lungs to expand normally during breathing.
Besides the active lung growth, the brain kicks in with brain wave activity for the visual and auditory systems.
Maternal Changes:
Your uterus is about 2 1/2 inches above your belly button. If you feel your uterus suddenly tighten and then relax, don't panic. You're experiencing "Braxton Hicks" Contractions. These are normal, usually painless or feel similar to menstrual cramps and happen at irregular intervals. They are your body's way of practicing for the real thing and help to tone up your uterus for the tough job of labor.
Are you eating well? You need about 300 extra calories now. Make them count!
