  • You may experience noticeable loss of amniotic fluid or the mucous plug may come away.
  • Labor can start any time so be familiar with the signs of labor and keep in contact with your health care provider.

Pregnancy To Do's

  • Check if you have done everything you need to do before the birth.
  • Continue to get rest.
  • Keep in contact with your health care practitioner, particularly if you notice changes in baby's movements, or signs of labor.
