This explains your chance of pregnancy after taking levonorgestrel (i‑Pill) the day before ovulation and when to test for pregnancy.

⚕️ What this likely means

• Because intercourse occurred the day before expected ovulation (a high‑fertility time), baseline pregnancy risk was relatively high.
• Levonorgestrel emergency contraceptive pill (ECP) works mainly by delaying ovulation; taken promptly it substantially reduces but does not eliminate the risk, especially when taken very close to ovulation.
• Practically, your remaining risk is lowered to a small but nonzero level (likely a few percent rather than zero); exact probability cannot be determined without testing.

🩺 When to take a pregnancy test

• For reliable home results, use a urine pregnancy test at least 21 days after the unprotected sex or 1 week after a missed period; testing earlier (≈10–14 days after sex) can give false negatives.
• A blood beta‑hCG (human chorionic gonadotropin) test detects pregnancy earlier (around 11 days after ovulation) and can be ordered by a doctor if you need earlier confirmation.
• If you vomited within 3 hours after taking the pill, its effectiveness may be reduced—mention this to the doctor.

⚠️ When to see a doctor

• See an obstetrician–gynecologist (OB‑GYN) if you get a positive test, your period is more than 1 week late, you have severe abdominal pain, heavy bleeding, or if you vomited soon after taking the pill.
• An OB‑GYN can arrange earlier blood testing, discuss repeat/alternative emergency options, and advise next steps.
