First trimester pregnancy in weeks

The first trimester is weeks 1-14. During the first trimester, both your and your baby’s body will be changing rapidly. It can be an overwhelming time emotionally and physically, especially for first-time moms and parents. This is also when many expecting moms experience symptoms such as fatigue, nausea, morning sickness and more.

Early on in the first trimester, your first prenatal visit should be scheduled to make sure that you and your baby are going to have a healthy pregnancy.

Find expert care for your pregnancy and schedule your first prenatal visit.

At The Mother Baby Center, we understand that it can seem like you have a million things to do over the course of the months that you’re pregnant. Normal weeks of pregnancy can fly by, and it can feel like there is too much to do and not enough time. Knowing what to expect throughout each week in a trimester of pregnancy can help you prepare, especially if you have a checklist of to-dos to guide you.

  • Weeks 1-3: During the first three weeks of pregnancy, you will have just been pregnant for a little under a month. Although doctors count back to the first day of your last period when counting weeks pregnant, the first two weeks you are actually not pregnant yet because you are still on your period. It is after the second week that conception, where the egg and sperm meet, will happen. During your third week of pregnancy, your baby will look like a little ball of cells.
  • Weeks 4-6: In weeks four through six, you will have been pregnant for just under two months. A lot will change during this time period. Your baby will grow from a little ball of cells to forming a brain, organs, a spinal cord and skin.
  • Weeks 7-9: By the end of week nine, you will be entering your third month of pregnancy. These weeks will also be full of rapid growth for the baby. You can expect your baby to have developed more features such as its head, nose and limbs.
  • Weeks 10-14: Congratulations! You are in the third month of pregnancy and almost done with your first trimester! During these last few weeks of the first trimester, you can expect your baby to be able to bend its limbs, make and release urine and develop genitals and fingernails.
