In medicine, pregnancy is defined as beginning when
the developing embryo becomes implanted into the endometrial lining
of a woman's uterus. In some cases where complications may have
arisen, the fertilized egg might implant itself in the fallopian
tubes or the cervix, causing an ectopic pregnancy.
Most pregnant women do not have any specific signs
or symptoms of implantation, although it is not uncommon to experience
light bleeding at implantation. Some women will also experience
cramping during their first trimester. This is usually of no concern
unless there is spotting or bleeding as well.
The outer layers of the embryo grow and form a placenta,
for the purpose of receiving essential nutrients through the uterine
wall, or endometrium. The umbilical cord in a newborn child consists
of the remnants of the connection to the placenta. The developing
embryo undergoes tremendous growth and changes during the process
of embryonic and fetal development.
Morning sickness afflicts about seventy percent of all pregnant
women, typically only in the first trimester
Most miscarriages occur during this period.
