What is a Trimester in pregnancy?
A trimester is a period of approximately three months during pregnancy. There are three trimesters in a pregnancy starting with the first day of the last menstrual cycle and ending with the delivery of the baby.
The first trimester is from week 1 to the end of week 12, the second trimester is from week 13 to week 28 and the third trimester is from week 29 to week 40.
How Long Does Each Trimester Last?
First Trimester (Weeks 1-12):
The first trimester lasts from the first day of the last menstrual cycle to the end of the 12th week of pregnancy. This is the period when the baby’s vital organs such as the brain, heart and lungs develop, as well as all other body systems.
Second Trimester (Weeks 13-28):
The second trimester is from week 13 to week 28. This is when the fetus grows rapidly, and the mother can start to feel the effects of pregnancy, such as a growing belly, increased appetite and feeling of movement.
Third Trimester (Weeks 29-40):
The third trimester is from week 29 to week 40. This is when the fetus continues to grow and the mother experiences a wide range of sudden changes, such as Braxton Hicks contractions, back pain and more frequent urination. This is also the time when the mother should prepare for labor and delivery.
Conclusion
Overall, a trimester of pregnancy lasts for 12 weeks each. The three trimesters of pregnancy are the first trimester, second trimester and third trimester. During each trimester, different developments occur in both the mother and the baby. It is important for mothers to keep track of the different developments in their pregnancy to ensure the health of the baby and mother.
