Changes in the mom's body during the first trimester of pregnancy.

During the first trimester (weeks 1–12), a mother’s body undergoes significant changes to support the developing baby:
Hormonal Changes:
Increased hCG, progesterone, and estrogen support pregnancy but can cause nausea, fatigue, and mood swings.
Breasts:
Tenderness, swelling, and darkening of the areolas are common as the body prepares for breastfeeding.
Uterus:
Begins enlarging to accommodate the growing embryo, leading to mild cramping or a sense of fullness.
Digestive System:
Morning sickness, bloating, and constipation occur due to hormonal changes and slowed digestion.
Weight Changes:
Minimal weight gain (1–2 kg) is typical; some women may lose weight due to nausea.
Fatigue:
Progesterone levels and increased energy demands can cause extreme tiredness.
Frequent Urination:
Increased blood flow to the kidneys and uterine pressure lead to more trips to the bathroom.
Emotional Changes:
Mood swings and heightened emotions are common due to hormonal fluctuations
.
Sense of Smell and Taste:
Enhanced sensitivity may trigger food aversions or cravings.
Circulatory System:
Blood volume increases, potentially causing dizziness or lower blood pressure.
These changes are normal, but medical advice should be sought for severe or unusual symptoms
