Congratulations on your pregnancy! As you embark on this incredible journey of bringing a new life into the world, you may be curious about what’s happening inside your body. During pregnancy, your baby goes through several stages of development before they are ready to enter the world. In this article, we will discuss the different stages of baby development during pregnancy.

The First Trimester (Weeks 1-12)

The first trimester is the initial stage of pregnancy, which starts from the first day of your last menstrual cycle and lasts till the end of the 12th week. During this period, your baby goes through the most critical stages of development. The fertilized egg implants in your uterus and starts to divide into different cells. The placenta also begins to form, which provides vital nutrients and oxygen to your growing baby. By the time you reach the end of the first trimester, your baby is about the size of a lime.

The Second Trimester (Weeks 13-27)

The second trimester is the stage where your baby’s growth becomes more visible. During this period, your baby’s organs continue to develop, and they start to move around in the amniotic fluid. Your baby’s eyes, ears, and taste buds start to develop, and they can now hear your voice and other sounds. By the end of the second trimester, your baby is about the size of a cauliflower.

In the final weeks of pregnancy, your baby moves down into your pelvis, getting ready for the big day.
