How to Prevent Pregnancy After Unprotected Sex: What You Need to Know in the Philippines

---

How to prevent an unwanted pregnancy is the most commonly asked question by ladies involved in unprotected sex. Even just once, sex can lead to pregnancy. If you find yourself in such a situation, it’s important to act quickly, understand your options, and get accurate, trustworthy care. In the Philippines, where abortion is illegal under virtually all circumstances, being informed about emergency contraception and prevention is especially crucial. (Wikipedia)

What Is “Post-Sex” Pregnancy Prevention?

Also known as emergency contraception (EC) or the “morning-after” methods, these options help reduce the risk of pregnancy after intercourse has occurred. They do not terminate an existing pregnancy. (World Health Organization)

Emergency contraception is most effective when used as soon as possible, and its effectiveness decreases with time. (World Health Organization)

Emergency Contraception Options Available in the Philippines

Here are the main methods you might be able to access in the Philippines:

1. Levonorgestrel Emergency Contraceptive Pill (ECP)

• This is a progestin-only pill (1.5 mg single dose or two 0.75 mg doses). It works by delaying or inhibiting ovulation and thickening cervical mucus, so sperm have more difficulty reaching the egg. (Wikipedia)
• It is most effective when taken within 72 hours (3 days) after unprotected sex. Some efficacy still exists up to 120 hours (5 days), but with lower effectiveness. (Healthline)
• In the Philippines, these emergency contraceptive pills are available in some pharmacies and via certain private suppliers. (PlanB Philippines)
• Note: They are not the same as an abortion pill and do not disrupt an established pregnancy. (PlanB Philippines)

2. Copper Intrauterine Device (IUD)

• A copper IUD (non-hormonal) can act as emergency contraception if inserted by a qualified provider within 5 days (120 hours) after unprotected intercourse. (Planned Parenthood)
• It is considered one of the most effective emergency methods (over 99% efficacy in some studies) and also serves as an ongoing birth control device if left in place. (Drugs.com)
• However, not all health clinics in the Philippines offer copper IUD insertions on an emergency basis, and access may be limited in rural or underserved areas. (PlanB Philippines)

3. Yuzpe Regimen (Combined Oral Contraceptives as Backup)

• In settings where dedicated emergency pills are unavailable, the Yuzpe regimen uses regular combined oral contraceptive pills (estrogen + progestin) taken in two doses (one immediately, the second 12 hours later). (Wikipedia)
• This method is less effective and has more side effects (nausea, vomiting, irregular bleeding) compared to levonorgestrel-only pills or the copper IUD. (Wikipedia)
• In the Philippines, some sources note that the Yuzpe method is one of the viable options, particularly in areas where “morning-after pills” are harder to access. (Hello Doctor)

Steps to Take Immediately After Unprotected Sex

Here’s a practical step-by-step guide:

1. Stay calm and act quickly. The sooner you use emergency contraception, the higher the effectiveness. (World Health Organization)
2. Access emergency contraception. Visit a trusted clinic, hospital, or pharmacy. Some online providers in Metro Manila or Luzon may offer same-day delivery for ECPs (check credentials carefully). (PlanB Philippines)
3. Consider the copper IUD if available and feasible—especially if 72 hours have passed or if you prefer a very effective option.
4. Take or administer the selected method. Follow medical advice carefully.
5. Follow up with a healthcare provider. Monitor for side effects, make sure your menstrual cycle returns, and consider a regular contraceptive method going forward.
6. Take a pregnancy test if your period is late.
7. Use condoms or barrier methods in future encounters to reduce both pregnancy risk and risk of sexually transmitted infections (STIs).

Barriers & Realities in the Philippines

• Many Filipinos are unaware of emergency contraception: a recent study cited that only 1 in 4 Filipino women know what emergency contraception is. (BusinessWorld Online)
• “Morning-after pills” are sometimes reported as unavailable or difficult to obtain in certain areas. Some sources say the best options currently are copper IUD insertion or using the Yuzpe method. (Hello Doctor)
• Legal, cultural, and religious beliefs can pose stigma, shame, or hesitation when seeking contraception services. (PlanB Philippines)
• The Responsible Parenthood and Reproductive Health Act (“RH Law”) of 2012 entitles Filipinos to access reproductive health services, including contraceptive access, but implementation and availability are uneven across regions. (Wikipedia)

Tips for Choosing & Maximizing Effectiveness

• If possible, choose the method that gives the highest efficacy for your situation (e.g. copper IUD, levonorgestrel ECP).
• Time matters: the sooner, the better. Don’t delay in seeking help.
• Know your cycle or when you might ovulate; if ovulation has already occurred, emergency pills are less likely to prevent pregnancy.
• Avoid self-medication with unproven remedies, douching, or herbal abortifacients—these are unsafe and ineffective.
• After taking EC, adopt a regular contraceptive method (e.g. pills, IUD, injectables, implants, condoms) to avoid future emergencies.
• Always verify the legitimacy of clinics, pharmacies, and suppliers, especially for online or delivery services.

Why Emergency Contraception Is Not an Abortion

A crucial distinction: emergency contraception prevents pregnancy; it does not terminate one. It acts by stopping or delaying ovulation, preventing sperm from meeting the egg, or altering the uterine environment so that implantation is less likely—but only before a pregnancy is established. (World Health Organization)

In the Philippines, abortion is illegal under nearly all circumstances, so safe and legal pregnancy prevention is especially important. (Wikipedia)

When to Seek Medical Help Immediately

• If you experience severe abdominal pain, prolonged heavy bleeding, or fever after using EC
• If you vomit within 2 hours after taking an emergency pill (you may need a repeat dose)
• If your period is delayed significantly or very irregular after EC
• If you suspect you might already be pregnant
• For STI testing or other sexual health concerns

The key is immediate action, consulting a trusted healthcare professional, and then adopting a reliable regular contraceptive method to minimize risk in the future.
