Pregnancy is an exciting, yet sometimes overwhelming, time, especially if it’s your first child. You want to do everything right, but the changes your body is going through to support the life growing inside can be overwhelming.
Whether this is your first pregnancy or your fourth, we’re here to help. A full-term pregnancy lasts between 37 and 42 weeks, and is divided into three trimesters—each lasting about 12 to 14 weeks. This simple guide will help you understand what to expect during each stage.
First Trimester: Weeks 1 to 13
Although you may not look pregnant yet, your body is already undergoing significant changes to support your growing baby. Hormone levels rise, your heart rate increases, and your body boosts its blood supply to deliver oxygen and nutrients to your baby.
Common symptoms during this time include:
- Morning sickness
- Fatigue
- Headaches
- Constipation
Your first doctor’s appointment typically takes place between 6 to 8 weeks after your last period. During this visit, your doctor will:
- Confirm your pregnancy with a urine or blood test
- Perform an ultrasound to check the baby’s health
- Order blood work to assess your nutritional levels and immunity
This first trimester is crucial for your baby’s development, as all major organs will form by the end of the third month. To support your baby’s health, follow these tips:
- Eat a balanced diet, avoiding shellfish and deli meats
- Take prenatal vitamins and folic acid
- Avoid smoking and alcohol
- Consult your doctor about any prescription medications you’re taking
Most importantly, keep an open line of communication with your doctor. Ask questions and voice any concerns—your health and peace of mind are essential for a healthy pregnancy.
Second Trimester: Weeks 13 to 27
The second trimester is often a more comfortable time for many women. Morning sickness may subside, and you may feel more energetic and sleep better. However, new symptoms may arise, such as:
- Leg cramps
- Backaches
- Nasal congestion
By now, your baby bump will start to show. This is a good time to buy maternity clothes and wear more comfortable, loose-fitting outfits. You may also notice an increase in appetite and weight gain, so be sure to discuss your weight and diet with your doctor at each appointment to stay on track.
The second trimester is also when most women feel their baby move for the first time, typically around 20 weeks. At this point, your baby can even hear and recognize your voice!
During this time, your doctor may perform various screenings and tests. Be prepared to share your complete medical, family, and genetic history, so your doctor can assess any potential risks for your baby.
An anatomy ultrasound is usually done between 18 and 22 weeks to check your baby’s growth and development. This scan examines key organs (heart, brain, lungs) and helps ensure they’re functioning properly. If you want to know the sex of your baby, this is when you’ll find out.
Third Trimester: Week 28 to Birth
You’re in the home stretch! In the third trimester, your doctor will start to see you more frequently to monitor your health and your baby’s progress. Your visits will include checks on:
- Blood pressure
- Baby’s heart rate
- Swelling in your hands and legs
- Protein in your urine
- Fundal height (the size of your uterus)
Your doctor will also check your baby’s position and assess your cervix to ensure your body is preparing for labor.
This is a great time to schedule your maternity photo shoot, ideally between your 7th and 8th months. Your belly will be well-defined, making it easier to capture that perfect shot. Taking them too early might not show your bump clearly, and waiting too long may make it harder to pose comfortably.
As your due date approaches, it’s a good idea to stay closer to home, as your baby may arrive early. Check with your doctor for any travel restrictions—most airlines require medical clearance for pregnant women to fly during the third trimester.
This is also a good time to enroll in a childbirth class with your partner. It will prepare you both for labor and delivery, and give you a chance to ask questions and learn what to expect.
Keep in mind that your due date is only an estimate. Your baby can arrive anywhere between 37 and 42 weeks, so it’s important to be ready for your little one at any time!
