The first trimester of pregnancy — spanning the first 12 weeks — is filled with excitement, questions, and often, a few surprises. If you’re wondering what to expect in the first trimester, you’re not alone.
This critical phase marks the foundation of your baby’s growth and your body’s adaptation to pregnancy. From early pregnancy symptoms like morning sickness to emotional ups and downs, here’s what you need to know.
Understanding the First Trimester (Weeks 1–12)
The first trimester of pregnancy begins on the first day of your last menstrual period and lasts until week 12. While you might not look pregnant yet, your body is undergoing massive changes. Key developments include:
Hormonal surges: Increased levels of hCG, estrogen, and progesterone.
Placenta formation: The life-support system for your baby begins to develop.
Embryo to fetus: Your baby transforms from a tiny cluster of cells into a developing fetus.
Common First Trimester Symptoms
Most women experience several early pregnancy symptoms as their bodies adjust. Common signs include:
Nausea and vomiting (morning sickness)
Fatigue during pregnancy
Mood swings due to hormonal shifts
Food cravings and aversions
Breast tenderness and bloating
Frequent urination
These symptoms are typically temporary, easing as you enter the second trimester.
Milestones to Watch for in Early Pregnancy
Tracking your pregnancy week by week helps you stay informed. Important early milestones include:
Positive pregnancy test (around week 4–5)
First prenatal visit (ideally between weeks 6–8)
Ultrasound to confirm due date and detect heartbeat
Blood tests and genetic screenings
These early check-ups set the stage for a healthy pregnancy.
