A pregnancy is divided into Three trimesters:

  • the first trimester is from week 1 to the end of week 12
  • the second trimester is from week 13 to the end of week 26
  • the third trimester is from week 27 to the end of the pregnancy.


The first weeks of your pregnancy are a vital time as your pregnancy gets established. While you get used to being pregnant, your body is busy building a baby. This is exciting moment.

For most women, the first trimester of pregnancy is so time consuming because everything is all so new, exciting and even overwhelming. This is the time to schedule early pregnancy appointments, confirm your pregnancy and have your doctor run tests, talk to your doctor if you feel sick, tired or having strange cravings.

The first trimester begins on the 1st day of your last period and lasts until the end of week 12, but there’s a lot more you need to know…
