Pregnancy is a crucial stage in a woman's life. During pregnancy, the woman experience multitude of transformation physically and psychologically to welcome the newborn. Therefore, it is always good to have a complete understanding of different stages of pregnancy for better care and to avoid complications. 


Normal full-term pregnancy in humans lasts for 40 weeks. It is divided into three trimesters: 1st trimester, 2nd trimester, and 3rd trimester.

 Let’s look in detail at different stages of pregnancy.


Among all trimesters, the 1st trimester is the crucial one. It is counted from 0 to 13 weeks, during which the organ and body structure of the baby develops. Besides, during this period, the mother experiences a variety of symptoms such as nausea, vomiting, breast tenderness, sore nipples, fatigue, etc. It is crucial to take extreme care during this period. Otherwise, it can lead to miscarriage and other complications.

The 2nd trimester of pregnancy lasts from 14 to 26 weeks of pregnancy. This stage is often called the 'golden stage', where most of the early pregnancy symptoms disappear. Also, during this period, the mother can feel movements of the unborn for the first time.

The 3rd trimester is the last stage of pregnancy, starting from 27 to 40 weeks. This is the stage where the baby is fully grown and waiting for his first cry. At the same time, mothers can experience over-excitement and anxiety during childbirth.
