13 Weeks

This is the last week of the trimester and the third month of pregnancy!  Next week begins week 14 and the second trimester.  Time has definitely gone by quickly.

This week Muffin is the size of a lemon.  Almost 3 inches long and almost 1 ounce in weight.  The baby's head is 1/3 the size of the whole body (rather than 1/2).  And he or she has vocal cords, teeth, and fingerprints.  This week the intestines have moved from the umbilical cord into the baby's abdomen.

At 13 weeks, the uterus is growing up and out of the pelvis.  The recommended weight gain for the next 27 weeks (trimesters 2 and 3) is 0.8 - 1.0 pound per week.  Slow and steady is the name of the game, and the ultimate goal is 25-35 pounds.  It's most important to eat a healthy, balanced diet and to exercise regularly.
