Your Developments

  • Your body is beginning preparation for giving birth in a couple of weeks.
  • Braxton Hicks (rehearsal/mock) contractions may become more frequent, the cervix begins to dilate, and the amniotic fluid starts to reduce in quantity.
  • Your weight gain is slowing down now.
  • You may also notice baby has dropped down into your pelvis (engaging/ lightening). This can occur 2 -4 weeks before the birth, especially for first time moms. It also often does not happen until labor starts - either way is normal.
  • Hopefully baby's head is facing head down, but if not, don't worry - talk to your health care provider about options for helping baby turn.

Pregnancy To Do's

  • Your Estimated Due Date is still a little way off but many babies can come early so be prepared just in case.
  • Pack your bag for hospital if you haven't already.
