What Is Postinor 2?
Postinor 2 is an emergency contraceptive pill containing levonorgestrel, a synthetic progestin hormone. It is commonly used after:
-
Unprotected sex
-
Condom breaks or slips
-
Missed birth control pills
-
Sexual assault
It works by:
-
Delaying ovulation — the release of an egg from the ovary
-
Preventing fertilization of the egg
-
Altering the endometrial lining to prevent implantation
It is not an abortion pill and will not work if you are already pregnant.
How Effective Is Postinor 2?
The effectiveness of Postinor 2 depends entirely on when it is taken after sex.
Time Taken After Unprotected Sex | Effectiveness |
---|---|
Within 24 hours | ~95% |
Within 48 hours | ~85% |
Within 72 hours | ~58% |
After 72 hours | Not effective |
The earlier you take it, the better it works.
Can You Still Get Pregnant After Taking Postinor 2?
Yes, it’s still possible to get pregnant after taking Postinor 2, especially in these situations:
1. Ovulation Already Occurred
Postinor 2 is most effective before ovulation. If the egg has already been released and fertilization occurs, Postinor 2 may not prevent pregnancy.
2. Taken Too Late
If taken more than 72 hours (3 days) after unprotected sex, the chances of it preventing pregnancy drop significantly.
3. Vomiting or Diarrhea
If you vomit within 2–3 hours of taking Postinor 2, your body might not absorb the medication. Similarly, severe diarrhea may reduce absorption.
4. High Body Mass Index (BMI)
Some studies suggest that women with a BMI over 30 may have reduced response to levonorgestrel emergency contraception.
5. Sex After Taking It
Postinor 2 does not provide protection for future sexual activity. If you have unprotected sex again after taking it, you will need another dose or a different contraceptive method.
How Do You Know If Postinor 2 Worked?
The first sign that Postinor 2 likely worked is getting your next period around the expected time. However, your cycle may be slightly early or late.
Watch for:
-
Period coming within 3 weeks
-
Mild bleeding or spotting (a common side effect)
-
No pregnancy symptoms
When to Take a Pregnancy Test
If your period is:
-
More than 7 days late
-
Unusually light or heavy
-
You experience pregnancy symptoms (nausea, sore breasts, fatigue)
Then take a urine pregnancy test or visit a clinic for a blood test.
What If You Get Pregnant After Taking Postinor 2?
If pregnancy occurs, it may be because:
-
Ovulation had already happened
-
The pill wasn’t absorbed properly
-
Sex occurred again after taking the pill
Is the baby affected?
Studies show no increased risk of birth defects if a pregnancy continues after taking levonorgestrel emergency contraception.
Still, consult a doctor for proper care.
Side Effects of Postinor 2
Most side effects are short-term and mild, including:
-
Nausea or vomiting
-
Headache
-
Breast tenderness
-
Dizziness
-
Fatigue
-
Menstrual changes
These usually resolve in a few days. If symptoms persist, consult a healthcare provider.
Can You Take Postinor 2 Twice in One Cycle?
Yes, you can, but it is not recommended due to:
-
Increased hormone load
-
Greater risk of menstrual disruption
-
Reduced effectiveness with repeated use
If you find yourself needing emergency contraception often, speak to your doctor about:
-
Regular contraceptive pills
-
Intrauterine device (IUD)
-
Implants or injections
How to Prevent Pregnancy More Effectively
While Postinor 2 is useful in emergencies, it is not meant for routine use.
For regular contraception, consider:
-
Birth control pills (combined or progestin-only)
-
IUDs (99% effective)
-
Contraceptive implants or injections
-
Male or female condoms
-
Fertility awareness methods (only with proper training)
FAQs:
1. Can I have unprotected sex again after taking Postinor 2?
No. It does not protect you after taking it. Use condoms or other contraception for the rest of your cycle.
2. Will it affect future fertility?
No. Postinor 2 does not affect long-term fertility.
3. What if I vomit after taking it?
If vomiting occurs within 2–3 hours, you should take another dose. Speak to a doctor.
4. Can I use Postinor 2 during my period?
Yes, though it’s unnecessary during menstruation because ovulation typically hasn’t occurred yet.
5. What’s more effective than Postinor 2?
-
Copper IUDs (can be used up to 5 days after sex, over 99% effective)
-
EllaOne (ulipristal acetate, effective up to 120 hours, but prescription-only in many countries)
Clinical Case Example
Case: A 24-year-old woman takes Postinor 2 48 hours after a condom broke. She experiences mild nausea and spotting. Her period arrives 3 days late but is normal in flow.
Outcome: This is a typical response. The pill likely worked, and minor delays are normal. No pregnancy test needed unless the next cycle is missed.
When to See a Doctor
Seek medical attention if:
-
Period is more than 7 days late
-
You have severe abdominal pain (possible ectopic pregnancy)
-
You’re unsure if the pill was taken correctly
-
You experience unusual bleeding patterns
-
You need long-term contraceptive advice
Conclusion
While Postinor 2 is a reliable emergency option, it is not 100% foolproof. Taking it early — ideally within 12–24 hours — gives you the best protection. But remember, it does not work if ovulation has already occurred, and it won’t protect you for future sexual activity.
If your period is late or abnormal after taking Postinor 2, take a pregnancy test and consult a healthcare provider.
For better reproductive control, consider switching to long-term contraception that suits your body and lifestyle.
