Pregnancy is divided into periods known as trimesters. The division of pregnancy is done in such a way so as to demarcate the various changes that take place in the woman’s body. The first trimester is characterized by irritating symptoms such as morning sickness. The second trimester is supposed to be the one that the woman enjoys the most as her body will be relatively comfortable during this stage. During the third trimester, her body will become heavy as her growing baby may become a little difficult to handle.
