Congratulations! You’re pregnant! This is an exciting time in your life, and you’re probably eager to learn as much as you can about your pregnancy. One of the first things you may wonder about is how pregnancy is measured. Pregnancy is typically measured in weeks, but how many weeks are there in a pregnancy?
How many weeks are there in a pregnancy?
A typical pregnancy lasts around 40 weeks or 9 months. However, pregnancy is measured in weeks, not months, and this can be a bit confusing. To calculate how many weeks you’ve been pregnant, you need to know the date of your last menstrual period (LMP).
The first day of your LMP is considered the first day of your pregnancy. From there, you count forward 40 weeks to estimate your due date. For example, if your LMP was on January 1st, your due date would be October 8th.
Why is pregnancy measured in weeks?
Pregnancy is measured in weeks because it’s the most accurate way to track fetal development. During the first few weeks of pregnancy, the fetus undergoes rapid development, and measuring in weeks allows healthcare providers to track this development more closely.
Additionally, using weeks as a measure of pregnancy allows healthcare providers to estimate a woman’s due date more accurately, which is important for planning prenatal care and delivery.
What are the different stages of pregnancy?
Pregnancy can be divided into three trimesters, each lasting around 12-14 weeks. Here’s a breakdown of each trimester:
First trimester (weeks 1-12): During the first trimester, the fertilized egg implants in the uterus and begins to develop into an embryo. By the end of the first trimester, the embryo has grown into a fetus that is around 3 inches long.
Second trimester (weeks 13-26): During the second trimester, the fetus continues to grow and develop. By the end of the second trimester, the fetus is around 14 inches long and weighs around 2 pounds.
Third trimester (weeks 27-40): During the third trimester, the fetus continues to grow and mature in preparation for birth. By the end of the third trimester, the fetus is around 19-21 inches long and weighs around 7-8 pounds.
What are some important milestones during pregnancy?
There are several important milestones during pregnancy, including:
First ultrasound: Your first ultrasound is typically done around 8 weeks of pregnancy. This ultrasound can confirm that you’re pregnant, determine your due date, and check for any potential complications.
Gender reveal: If you want to find out the sex of your baby, you can typically do so around 20 weeks of pregnancy.
Vital tests: There are several important tests that are done during pregnancy, including blood tests to check for any potential issues and a glucose tolerance test to check for gestational diabetes.
Braxton Hicks contractions: Braxton Hicks contractions are “practice” contractions that can start as early as the second trimester. These contractions help prepare your body for labor and delivery.
What are some common pregnancy symptoms?
Pregnancy can come with a variety of symptoms, including:
Nausea and vomiting: Many women experience nausea and vomiting during the first trimester, which is commonly referred to as morning sickness.
Fatigue: Pregnancy can cause you to feel more tired than usual, especially during the first and third trimesters.
Frequent urination: As your uterus expands, it can put pressure on your bladder, causing you to need to urinate more frequently.
Food cravings and aversions: Many women experience food cravings and aversions during pregnancy, which can be caused by hormonal changes.

While pregnancy can be an exciting time, it can also come with a variety of symptoms, including nausea and vomiting, fatigue, frequent urination, and food cravings and aversions. If you’re experiencing any concerning symptoms, it’s important to talk to your healthcare provider.
