What to Expect in Your First Trimester of Pregnancy

Congratulations on your pregnancy! The first trimester of pregnancy is a time of rapid changes for both you and your baby between weeks 0-12 weeks. Here’s what you can expect in the coming days.

Physical Changes

Morning Sickness

Many women experience nausea and vomiting, commonly referred to as morning sickness, which can actually occur at any time of day. Eating small, frequent meals and staying hydrated can help. Grab some Queasy Pops to help with nausea in between meals.


Your body is working overtime to support your growing baby, which can lead to exhaustion. Listen to your body and rest when you need to.

Breast Changes

Your breasts may feel tender, swollen, or fuller as they prepare for breastfeeding. Wearing a comfortable, supportive bra can help alleviate discomfort.

Emotional Changes

Mood Swings

The influx of hormones in your body can cause emotions to run high. It’s perfectly normal to feel a rollercoaster of feelings during this time.


It’s common to worry about your baby’s health, motherhood, or how a baby will change your life. Reach out to friends, family, or professionals for support.

Prenatal Care

Regular check-ups with your healthcare provider are crucial. These visits typically involve:

  • Assessing your health history
  • Blood tests and other screenings
  • Monitoring your blood pressure
  • Tracking the baby’s growth and heart rate

Lifestyle Adjustments


Eat a balanced diet rich in vitamins and minerals. Prenatal vitamins, particularly those containing folic acid, are often recommended.


Most exercise is safe during pregnancy, but it’s best to consult with your healthcare provider on what’s best for you.

Substances to Avoid

Stay away from alcohol, tobacco, and other harmful substances that could affect the baby’s development. This is important not just in your first trimester of pregnancy but all three.

Listeriosis Prevention

Avoid unpasteurized dairy products and certain deli meats to prevent listeriosis, an infection harmful to your baby.

Baby’s Development

By the end of the first trimester:

  • Your baby will be about the size of a peach.
  • Vital organs, such as the heart, kidneys, brain, and lungs, begin to form.
  • Facial features like eyes and ears start to emerge.
  • Limbs are formed, and fingers and toes begin to take shape.
