Had Unprotected Sex? A Calm, Step-by-Step Guide to Emergency Contraception and Pregnancy Testing

This is a practical, judgement-free timeline. Emergency contraception is legal, safe and widely available in India. What matters most is time.

Step 1: Within the first few hours

• Note the exact date and time of unprotected sex (or condom failure).
• Don’t rely on period-tracking apps or calendar “safe days” — they are only estimates. If pregnancy is not wanted, consider emergency contraception whatever day of your cycle it is.

Step 2: Within 72 hours — the emergency pill

• Take a levonorgestrel 1.5 mg emergency contraceptive pill (sold in India without prescription, e.g. i-Pill, Unwanted 72) as early as possible. It works better the sooner it is taken.
• The dose is 1.5 mg — one tablet.
• It is not an abortion pill. It mainly works by preventing or delaying ovulation. It cannot end a pregnancy that has already started (WHO).

Talk to a doctor or nurse the same day if:

• Your period is already late, or you may already be pregnant
• You take medicines for epilepsy or tuberculosis (e.g. rifampicin), certain HIV medicines, griseofulvin or St John’s wort — these can make the pill less effective
• You have severe liver disease, a condition affecting absorption, previous bariatric surgery, or a higher body weight — another method (like a copper IUD) may work better
• You had unprotected sex more than once in the same cycle

Step 3: More than 72 hours? Don’t give up

• Emergency contraception may still be possible up to 120 hours (5 days).
• A copper IUD (Copper-T) inserted by a trained provider within 5 days is the most effective emergency contraception — over 99% effective (WHO). It can also be kept as ongoing contraception. It is available free at government health facilities.
• Ulipristal acetate 30 mg works better than levonorgestrel between 72 and 120 hours, but it may not be easily available in India — ask a doctor. Two things matter if you take it: do not take a levonorgestrel pill as well, and do not start or restart hormonal contraception (pills, injection, implant) for 5 days afterwards, because it can make ulipristal less effective — use condoms for at least 7 days after restarting (CDC Selected Practice Recommendations). After a levonorgestrel pill, hormonal contraception can be started immediately, with condoms for 7 days.

Step 4: After taking the pill

• Temporary nausea, tiredness, spotting, belly discomfort, or an earlier or later period can happen.
• If you vomit within 2 hours of taking the tablet, you may need another dose — contact a pharmacist or doctor (WHO).
• The pill does not protect you if you have unprotected sex again later in the same cycle. Use condoms and discuss a regular contraceptive method.
• Emergency pills are for emergencies — they are less effective than regular contraception. Your nearest health centre can advise on regular methods, many of which are free.

Also think about infections (STIs and HIV)

• Emergency contraception does not protect against sexually transmitted infections.
• If HIV exposure is possible, ask about HIV post-exposure prophylaxis (PEP) the same day. A doctor decides whether it is needed, based on the type of exposure and what is known about the partner — it is not given for every exposure. When it is indicated, PEP must start as soon as possible and within 72 hours (WHO 2024). Go to a government hospital or ART/ICTC centre quickly.
• Watch for unusual discharge, sores, burning while passing urine or pelvic pain, and get tested if advised.

Step 5: Wait for the right time to test

A test the next morning or just a few days after sex is too early to detect pregnancy.

Your cycle	When to do a urine pregnancy test
Regular periods	From the first day your period is missed
Irregular periods / unsure	At least 21 days (3 weeks) after the last unprotected sex

How to use a urine pregnancy kit

• Check the expiry date and read the kit’s own instructions.
• Preferably use the first urine after waking up, especially when testing early. Don’t drink lots of water before the test.
• Use the number of drops or dipping time given, and read the result only within the stated time.

Result window	Meaning (most kits)
Only the C (control) line	Negative
Both C and T lines — even if T is faint	Positive
No C line	Invalid — repeat with a new kit

Is a beta hCG blood test compulsory?

No. A doctor may advise it if the urine result is unclear, pregnancy is strongly suspected despite negative tests, the period stays absent, or there are worrying symptoms. It usually doesn’t need fasting, and sometimes needs repeating.

If the test is negative

• If you tested early, don’t assume pregnancy is ruled out — repeat after 48–72 hours or a few days, using morning urine, and in any case do a test at least 21 days after the last unprotected sex.
• If a correctly timed repeat test is also negative but your period still hasn’t come, stay calm and see a gynaecologist. Stress, PCOS, thyroid or prolactin problems, weight changes or heavy exercise can delay periods.
• Don’t take random tablets “to bring periods” without finding the reason.

If the test is positive

• Don’t self-medicate. Don’t take any pills bought without a prescription.
• See a registered doctor or government health facility early to confirm the pregnancy, check its location and discuss your options safely and legally.

Key takeaways

1. Act fast: levonorgestrel 1.5 mg as soon as possible, ideally within 72 hours.
2. After 72 hours, see a doctor the same day — a copper IUD within 5 days is the most effective option.
3. It is not an abortion pill and does not protect against STIs or later sex.
4. Test on the missed-period day, or 3 weeks after sex if cycles are irregular.
5. Positive test or worrying symptoms → see a doctor; never self-medicate.
