Changes occur during 6th week of pregnancy

Baby's Development -

Baby’s brain and nervous system are developing at a rapid pace. Optic vesicles, which later form the eyes, begin to develop this week on the sides of the head. Baby's heart will begin to beat around this time, and it may even be detected on ultrasound examination. And the beginnings of the digestive and respiratory systems are forming. Small buds that will grow into baby's arms and legs also appear this week. Making a full- length measurement difficult, babies often are measured from the crown to rump rather than from head to toe. This week, baby only measures 2 to 5 millimeters from crown to rump. The embryo is starting to look like a little tadpole but the ‘tail bone’ will disappear and become the coccyx.


Woman's Body -

Common pregnancy complaints may hit in full force this week. 
  • Woman may feel extreme fatigue as body adjusts to the demands of pregnancy. 
  • Tender, aching breasts and nausea and vomiting (morning sickness) may leave her feeling less than great. 
  • Morning sickness can occur at any hour or all day. 
  • Nausea isn't the only thing that has she running to the toilet, though — hormonal changes and other factors, such as kidneys working extra hard to flush wastes out of her body, this may lead to urinate more frequently.
