Making sense of pregnancy can be difficult, especially if this is your first baby. But understanding each stage (also called “trimester”) can help you feel more prepared for the bodily changes you’ll undergo.
There is a wealth of information online about pregnancy, and you can even download pregnancy tracking apps to learn about your baby’s development, their estimated size and weight, and more. But sometimes, it can feel reassuring to speak with someone about your pregnancy.

Understanding Trimesters
There are three trimesters in a typical pregnancy. Each trimester lasts about three months, though you’ll often hear your provider refer to your pregnancy by the number of weeks.
Each trimester includes critical stages of fetal development. You’ll feel your body change as the baby grows and you prepare to give birth.
First Trimester
The first trimester occurs from conception to 12 weeks gestation. Each week holds new milestones for your baby’s development.
In the initial weeks, fertilization occurs. You likely won’t know you’re pregnant until about the 5th week of pregnancy.
As the first trimester continues, the small bundle of cells will turn into an embryo and then develop into a fetus after 8 weeks gestation. The fetus’s major bodily systems are developing, their eyes become visible, and by week 12, their limbs, organs, bones, and muscles are all present.
During the first trimester, you may experience common pregnancy symptoms like nausea, fatigue, frequent urination, tender breasts, and an increase in mood swings.
Second Trimester
By your second trimester, any nausea or vomiting has likely disappeared. The fetus can suck their thumb, yawn, and more.
You’ll likely feel movement (similar to a flutter) by the end of your fifth month of pregnancy. You’ll have an anatomy scan at around 20 weeks gestation for a more in-depth look. The sonographer or ultrasound technician will take measurements and note any issues requiring medical attention or monitoring. They may even inform you of your baby’s sex.
This trimester is often more comfortable; most pregnancy symptoms may have vanished. Your baby will become more active in your uterus and respond to light and sounds.
Third Trimester
When you reach the third trimester, you’re in the home stretch. Your due date is approaching, and your baby is gaining weight quickly. You will also notice them moving often, which can be uncomfortable.
Your baby is considered full-term at 39 weeks gestation, though some babies are born earlier. Their position should be head-down in your uterus, though some babies are breech (when their feet are positioned down).
This can be a time of great anticipation and nervousness. Your healthcare provider will monitor you for signs of labor, though you’ll likely be especially aware of any changes during these weeks.
Remember, your body has done the hard work of helping your baby grow and develop. The wait is almost over.
