    Week 22 of Pregnancy: Week by Week Pregnancy Calendar

    Your baby is now the size of a spaghetti squash, measuring between seven and a half (7.5) and eight (8) inches from crown to rump (or eleven [11] inches from head to heel) and weighing about one (1) pound. You are in your sixth month of pregnancy.

    Your Baby

    Pancreas

    Pancreas

    During week 22 of pregnancy, your baby is beginning to look like a miniature newborn. Layers of fat continue to develop beneath the skin, plumping up your baby’s still skinny body. The eyebrows and eyelashes are even more distinct, and your baby may even have some hair on the top of his or her head now. The lips are also more distinct. The irises, which are the colored part of the eyes, have formed but still lack the pigment that will eventually be your baby’s bright blues, browns, or greens. Your baby continues to respond to both sound and light.

    Inside your baby’s body, the pancreas, which is the organ that is essential for the production of some important hormones including insulin, continues to develop and mature. Your baby’s muscles are getting stronger every day, which you can attest to as your baby punches, kicks, and twirls inside your abdomen. The brain is growing daily, and nerve endings develop. The senses also continue to develop during week 22 of pregnancy. Your baby can move and wiggle his or her fingers and may even reach for his or her own face or the umbilical cord in exploration with the newly developed sense of touch. Your baby continues to breathe amniotic fluid in and out, which helps the lungs practice breathing.

    During week 22 of pregnancy, your belly continues to expand in size. You should gain about one to two pounds per week from now until you give birth for a total weight gain of twenty-five to thirty-five pounds. As the pregnancy hormone relaxin begins to relax the ligaments in your body in preparation for the birth, you may also notice that your feet are getting slightly bigger. Relaxin does not discriminate between the ligaments in your pelvis and the ligaments in the rest of your body, so the ligaments in your feet may also stretch a little. In fact, some women go up a half or even a whole shoe size during pregnancy. Other symptoms during week 22 of pregnancy include heartburn, indigestion, constipation, flatulence, increased vaginal discharge (leukorrhea), faintness, dizziness, leg cramps, and slight swelling of the ankles and feet.
