Pregnancy lasts about 40 weeks, counting from the first day of your last normal period.
Both the mother and the baby go through many changes during this time. These changes are grouped into three time periods called "trimesters".

As you near your due date, a woman's cervix becomes thinner and softer (called effacing). This is a normal, natural process that helps the birth canal (vagina) to open during the birthing process. Your doctor will check your progress with a vaginal exam as you near your due date.
