Mother:
You may find yourself with a stuffy nose. Nasal congestion and nose bleeds are fairly common during pregnancy. Try using a vaporizer or humidifier to help lessen the symptoms. You continue to feel tired, nauseated, and possibly dizzy. Making a baby is hard work! Baby:
We have elbows! Your baby is now approximately 13-17 mm crown to rump length, or about 0.51 - 0.66 inches. S/he also weighs in at 1 gram! Toe rays are present as the toes begin to form. Gonads have become testes (for boys) or ovaries (for girls). Baby will move away if touched through the uterine wall, and can spontaneously move as well. Ossification (hardening) of the bones may begin.
Twin Tips:
Weight gain in a multiple pregnancy is going to be a big issue. By 24 weeks Dr. Luke in her book, When You're Expecting Twins, Triplets or Quadruplets suggests by 24 weeks that a twin mom gain 24 lbs, a triplet mom gain 36 lbs and a quadruplet mom gain 50 lbs. After that the rate of weight gain should be about 1/2 lb per week, per baby.
