Your Developments

  • Breasts may feel tender.
  • You may be experiencing some morning sickness.
  • Morning sickness occurs because increased hormone activity slows down your digestive system, apparently to enhance the absorption of nutrients for your baby.
  • The placenta grows to cover one-fifteenth of the uterine interior.

Pregnancy To Do's
