Emergency Contraception

emergency contraceptives, family planning, reproductive health

At A Glance:

  • Contraceptive pills or copper IUDs can both be used as emergency contraception after unprotected sex to decrease the chances of pregnancy.
  • Should only be used after unprotected sex, if another contraceptive method failed, or if no contraception was used.
  • Can be used up to five days after unprotected sex. Pills can be up to 88% effective if taken within 72 hours (three days) after unprotected sex. The sooner, the better.
  • The Yuzpe Method is not guaranteed as effective as daily intake of pills as a regular contraceptive method.
  • Copper IUDs are 99.9% effective if inserted within 120 hours (five days) after unprotected sex.

What Is It

Emergency contraception lessens the chances of a woman getting pregnant if taken within the first few days after unprotected sex. It should be taken as a last resort when other contraceptive methods failed or were not used during unplanned sex.

You may want to use it if:

  • you weren’t using any contraceptive when you had sex
  • you forgot to take your pills or use condoms
  • your partner’s condom broke or slipped off
  • your partner didn’t pull out in time or
  • you were forced to have unprotected vaginal sex

Emergency contraceptive pills are also called “morning after pills,” which gives the wrong impression that they should be taken the morning after unprotected sex, when in fact, they can already be taken as soon as possible without having to wait for the morning after.

In the Philippines, the daily oral contraceptive pills available can be used as emergency contraception through a specific method. The Yuzpe Method prevents pregnancy before it happens; it’s a backup plan, and should not be done regularly. If you are interested in taking oral contraceptive pills as a regular method of contraception, consult your healthcare provider to know more. It is also strongly advised to consult a healthcare provider when using the Yuzpe Method.

Copper IUDs are available in the Philippines, and can also be used as emergency contraception in case of unprotected sex. If inserted by a healthcare provider within 120 hours (five days) after the incident, it is up to 99.9% effective—even on the fifth day— and can be left for up to ten years if you have decided to use it as an ongoing contraceptive method. This makes the copper IUD the most effective emergency contraception. Although the initial cost is quite a bit more expensive, it’s highly effective for years. Talk to your healthcare provider if you want to know more about getting an IUD.

How It Works

Pregnancy doesn’t happen immediately after sex, which is why preventing it after unprotected sex is still possible. Take note: it can take up to seven days for the sperm cell and egg cell to meet after sex.

Pills prevent the sperm cell and egg cell from meeting and result in pregnancy by releasing a large dosage of the hormones estrogen and progestin in the body. Through this, the egg cell is stopped or delayed from leaving the ovary and traveling to the uterus for fertilization.

The Yuzpe Method lessens the chances of pregnancy to happen if taken within the first few days after unprotected sex; however, how much the chances are reduced depends on how soon the pills are taken after the incident, and at what stage the woman’s menstrual cycle is already when she takes it. The chances of getting pregnant are higher when the woman had unprotected sex during the 2nd or 3rd week of her menstrual cycle; this makes the effectiveness rate not absolute. It’s always better to use a regular form of contraception, such as a condom or the daily oral contraceptive pills.

Copper IUDs work as an emergency contraceptive because they affect how sperm cells move, and thus preventing them from meeting an egg cell up to five days after unprotected sex. In case the egg cell was fertilized by a sperm cell, the copper IUD also prevents the fertilized egg cell from implanting itself in the uterine lining, which prevents pregnancy once again.

How To Use It

Do the Yuzpe Method as soon as possible after unprotected sex. Although it can reduce the risk of pregnancy if used within 72 hours after the incident, taking it sooner makes it more effective.

Take four (4) Ethinyl Estradiol 30mcg/Levonorgestrel 150mcg pills as soon as possible. Follow this with another dose of four (4) pills 12 hours later. You should be able to take a total of eight (8) pills.

If vomiting occurs within 2 hours after taking either of the doses, you need to repeat that dose. Remember, the sooner the pills are taken, the better.

It’s normal for your next period to be different from normal after taking emergency contraception.

  • It may come earlier or later than usual
  • It may be heavier, lighter, more spotty, the same as usual

You may also feel dizzy and nauseous after taking the pills.

If you have a copper IUD inserted within five days of unprotected sex, it can lower the chances of pregnancy by 99.9%. To undergo the procedure, you’ll have to make an appointment with a healthcare provider.

The Positives

  • Pregnancy can be prevented after unprotected, unplanned or unsolicited sex.
  • Offers more protection and peace of mind than doing nothing.
  • Easy to use.
  • Copper IUDs are 99.9% effective and can be used for up to ten years.

The Negatives


  • Can cause an upset stomach and vomiting.
  • Could cause breast tenderness, irregular bleeding, dizziness, headaches (short-term), and temporary changes to the menstrual cycle.
  • The Yuzpe Method should be done.

Copper IUD

  • May cause cramping after insertion
  • Might lead to heavier or longer periods
  • Need to make an appointment with doctor for insertion

  1. Hi, my partner used Yuzpe method last week. Unluckily condom broke tonight. Is it still advisable for her to do the yuzpe method? (We’re using althea btw) I’m just concern about her health that doing yuzpe method again this week may harm her.

    1. Hi! The Yuzpe Method do not have long-term effects on health. It’s proven safe by doctors and experts. If you really read this article, you would know that. However, Althea is not effective for the Yuzpe Method.

  2. Hi,
    I’m new to BCP. I started mine last April 27 at 1:01pm. This is my 9th day of using it. Btw, used it a month of not having a period. Cause I’m irreg.
    My question is, should I do the Yuzpe method while on BCP or Trust Lady pills? My partner came inside me this morning of May 5, 5 am. Took my 9th pill this 1:01 pm. I’m just concerned if I will not get pregnant. And if there’s a chance. Should I use Yuzpe method. Pls. I need andwers.

    1. Hi Ladie! If you are taking your BCP correctly and consistently without skipping a day, you are fully protected and do not need to do the Yuzpe Method. You may read this article again to know when the Yuzpe Method is recommended.

  3. Hi just want to ask.. I completed the yuzpe method last April 6..expected menstruation date should be april 21..im 10 days delayed.. Im worried..

    1. Hi Lady! The Yuzpe Method may cause some changes in your next menstruation, such as delaying it. If you are worried that you are pregnant, take a pregnancy test to find out.

      1. Nagcheck ako today.. NEGATIVE.. Dalawa binili ko.. Parehas negative.. Need ko ba ulitin ung PT? Delayed pa din aq up to now

      2. Hi Lady! Kung wala po kayong tiwala sa PT, baka mabuting magpunta na lang po kayo sa obgyn o sa malapit na health center para kayo’y masuri.

  4. hi just a follow up question, is lady pills (4 pills on 1st dose then another 4 on 2nd dose) ok for yuzpe method? thanks!

  5. hi.. i got my 1st day of period last apr 16 then had unprotected sex apr 26. i already took 4 lady pills on same day apr 26 and will be taking the second dose after 12 hrs. will this still be effective given that i was on my 10th day of my cycle? thanks

    1. Hi Yvette! Yes, doing the Yuzpe Method is up to 88% effective, but do remember that it does not completely eliminate the risk of pregnancy especially if you are ovulating on the day of the incident.

      1. hi im experiencing light abdominal cramps and light period today, one week before my expected period. is this normal? thank you

  6. Hello, I used Trust (Yuzpe method) on March 7, around 23hrs after sex. We used a condom but it might have leaked so I took ECP just to be sure. I got my period on March 21, and it was right on time. I’m sure it was my menstruation (not just withdrawal bleeding) because it had the usual flow and lasted for 4-5 days. However, for this month, my period is almost a week delayed already. I also experience nausea from time to time. Is this still a side effect of the ECP? I haven’t been sexually active since too. I took Nordette before as an ECP, and I haven’t experienced this with it.

      1. Hello again, just want to do a follow-up. I got my period yesterday. So my 2nd period after Yuzpe was very delayed – I skipped a whole month. But what’s really weird were the PMS/pregnancy-like symptoms I experienced after my period/withdrawal bleed. Last month, I experienced nausea, fatigue, back ache, head ache, and cramps in different variations. Just putting this out there so other women would know that they could also experience some side effects a month after taking ECP. Your hormones could be all over the place. 😀

      2. Hi Glaze! Thank you for sharing your experience with the other women here. Good to know that you’re all right now. Stay safe, and don’t forget to Do It Right!💜

  7. i got withdrawal bleeding (Feb 22) after 5 days of yuzpe. it was heavy and lasted for 5 days. until now i haven’t got my period yet. is it normal for periods to be delayed after doing yuzpe?

      1. but until now i still have no period, is it really normal? I haven’t got my expected period last March.

        and how long is usually the delay? thanks po
