Early Pregnancy Symptoms: Timeline and When to Test

Symptoms can appear as early as 1 week post‑conception (around implantation), but most women notice changes 2–4 weeks after a missed period.

Common Early Signs

• Fatigue (progesterone effect)
• Nausea ± vomiting (“morning sickness”)
• Breast tenderness, swelling
• Frequent urination
• Bloating, mild cramping
• Mood swings
• Light spotting (implantation bleeding)

Confirmation

• Home urine hCG test: accurate ~1 week after missed period.
• Serum β‑hCG: quantitative, detects pregnancy earlier.
• Ultrasound: confirms intrauterine pregnancy at ~5–6 weeks gestation.

See a clinician for prenatal care initiation once pregnancy is confirmed.
