Pregnancy Symptoms vs. Other Causes: When to Test and See a Doctor

Common Pregnancy Symptoms

• Missed period (most reliable early sign)
• Nausea/vomiting ("morning sickness")
• Breast tenderness, swelling, areolar darkening
• Fatigue, frequent urination
• Food aversions/cravings, smell sensitivity
• Mild cramping, spotting (implantation)
• Mood changes, bloating, constipation

Why Symptoms ≠ Pregnancy

• PMS: Overlapping symptoms (breast tenderness, bloating, mood swings).
• Hormonal fluctuations: Stress, thyroid, PCOS, perimenopause.
• Gastrointestinal: GERD, gastritis, food poisoning.
• Medications: Hormonal contraceptives, fertility drugs, psychotropics.
• Psychological: Strong desire/fear of pregnancy can amplify somatic awareness.

Testing & Next Steps

1. Home pregnancy test: First morning urine, after missed period. Repeat in 48h if negative.
2. Serum quantitative hCG: Detects pregnancy earlier, quantifies levels.
3. Ultrasound: Confirms intrauterine pregnancy, viability, dating (≥5-6 weeks).

When to Seek Care

• Positive test → initiate prenatal care.
• Negative test but persistent symptoms → evaluate for other causes.
• Abdominal pain + vaginal bleeding → rule out ectopic pregnancy (emergency).
• Severe nausea/vomiting → assess for hyperemesis gravidarum.

Early prenatal care improves maternal and fetal outcomes.
