Pregnancy is measured in trimesters from the first day of your last menstrual period (LMP) and normally lasts about 40 weeks from conception to the birth of a baby. This time is roughly divided into 3 periods: the first trimester, second trimester and third trimester. This application will show you, how the baby growth will be in these three trimesters. This will be very useful for the pregnancy ladies, through which they can take care of the baby in these 41 pregnancy weeks.
