Changes occur during 13th week of pregnancy

Baby's Development -

As woman begin the second trimester of pregnancy, placenta has developed and is providing to baby with oxygen, nutrients, and waste disposal. The placenta also produces the hormones progesterone and estrogen, which help to maintain the pregnancy. Baby's eyelids have fused together to protect the eyes as they develop. Baby may also be able to put a thumb in his or her mouth this week, although the sucking muscles aren't completely developed yet.


Woman's Body -

  • Woman may start to develop a dark line from tummy button (navel) to pubic hair. This is called the ‘linea nigra’. It is caused by increased pigmentation in skin. It will fade after childbirth.
  • Nipple might go a darker colour too. This is also caused by increased skin pigmentation.
  • At first prenatal appointment, health care provider probably gave a prescription for prenatal vitamins. Taking these supplements, in addition to eating a healthy diet, ensures baby gets additional vitamins and minerals, such as folic acid, zinc, iron, and calcium, which are necessary for growth and development.
