Stages of Pregnancy (by trimester & weeks)

First Trimester (Week 1–12)

• Begins at the first day of your last menstrual period (LMP)—even before conception occurs around week 2.

• Critical developments: implantation, embryo formation, major organ and system development.

• Common symptoms: fatigue, breast tenderness, nausea (morning sickness), frequent urination, mood swings, food cravings or aversions.

Second Trimester (Week 13–28)

• Major growth phase: organs continue maturing, the fetus gains weight; mother’s abdomen expands.

• Milestones: first fetal movements ("quickening") typically felt around weeks 16–20.

• Symptoms often ease, making this the "honeymoon" period of pregnancy.

  • Early term: 37 0/7 – 38 6/7 weeks

  • Full term: 39 0/7 – 40 6/7 weeks

  • Late term: 41 0/7

Pregnancy unfolds in three stages, each with its own changes and milestones:

1. First Trimester (Weeks 0–13):
   Your baby's core organs form during this critical phase. You may experience nausea, fatigue, and hormonal shifts as your body adjusts.

2. Second Trimester (Weeks 14–26):
   Often called the “honeymoon phase,” this is when energy returns and you might start feeling the baby move. Many physical discomforts ease.

3. Third Trimester (Weeks 27–40):
   Your baby grows rapidly in size and weight, and your body prepares for birth. This stage can bring more frequent doctor visits, fatigue, and anticipation as your due date approaches. https://womenshealth.gov/pregnancy/youre-pregnant-now-what/stages-pregnancy
