1. What is the First Trimester of Pregnancy?

The first trimester starts from week 1 (even before conception if you count from your last period) and lasts through week 12. It’s a time of rapid development for your baby and crucial care for your body.

Key Highlights:

• Fertilization and implantation occur
• Baby’s heart starts beating by week 5–6
• Organs like the brain, spine, and heart begin to form
• Pregnancy hormones (hCG, estrogen, progesterone) rise significantly

2. Common Symptoms in the First Trimester

Pregnancy affects every woman differently, but here are some common first trimester symptoms:

a. Fatigue

Rising progesterone levels make you feel exhausted. Listen to your body — rest is crucial.

b. Morning Sickness

Nausea and vomiting may occur anytime, not just in the morning. It typically starts around week 6.

c. Breast Tenderness

Hormones prepare your body for breastfeeding, causing swelling and soreness.

d. Frequent Urination

The growing uterus and hormonal changes affect your bladder.

e. Mood Swings

Hormonal shifts can trigger emotional highs and lows. Support from your partner or family helps.

f. Food Aversions or Cravings

Your taste preferences may change drastically.

g. Bloating and Constipation

Hormones slow digestion, so include fiber-rich foods and stay hydrated.
