Early Pregnancy Signs: Bloating, Sore Nipples, Frequent Urination, Fatigue

Common first-trimester symptoms (often starting 4–6 weeks after last period):

• Bloating: Progesterone relaxes GI smooth muscle → slowed digestion, gas.
• Sore/Sensitive Nipples & Breasts: Estrogen/progesterone stimulate ductal growth; tenderness, tingling, heaviness.
• Frequent Urination: hCG ↑ renal blood flow; growing uterus presses bladder.
• Fatigue: Progesterone’s sedative effect; metabolic demands of placentation.
• Light Spotting (Implantation Bleeding): 6–12 days post-ovulation; lighter, shorter than period.
• Nausea/Vomiting: “Morning sickness” (any time); peaks ~9 weeks.
• Mood Swings, Food Aversions, Constipation, Headaches.

Confirm Pregnancy: Home urine test (detects hCG) after missed period. Blood test (quantitative hCG) earlier. See OB/GYN for prenatal care initiation.

Symptoms vary widely—some women have few. Absence of symptoms ≠ non-viable pregnancy.
