Your little strawberry-sized baby is now about the size of a plum. They are 2.1 inches (5.4 cm) and weigh 2 ounces (58 grams).

Your baby can open its mouth and wiggle its little fingers and toes. Brain development is in high gear, fetal nerve cells multiply rapidly, and synapses start firing. This week marks a turning point for your baby, where they go from developing new bodily structures to the maintenance phase. Your baby will continue to mature the systems already set up and get all the organs to function before birth. Your baby’s digestive system is beginning to practice contraction movements, which your baby will need after birth to digest food. The bone marrow is busy making white blood cells to help your baby fight infection.


Your uterus has moved from the pelvic floor to the front of your abdomen. This shift may temporarily ease the pressure on your bladder. Between now and week 16, your lower uterine corpus unfolds, which allows your uterus to become more spherical. This allows more room for your baby with minimal stretching of the uterus.

Several common oral health conditions can occur in pregnancy. Approximately 40% of pregnant women have some form of periodontal disease. The American College of Obstetricians and Gynecologists recommends that you see a dentist during pregnancy and that cleanings and x-rays are safe. Make dental care a priority and schedule an appointment.
