The Condom Broke! Do I Need To Take Emergency Contraception? Will It Affect My Ability To Have Kids In The Future?

Today, many couples are depending on condoms as their primary method of birth control. But what happens when the condom suddenly breaks and panic ensues? This is where emergency contraception (EC) or “the morning after pill” comes into play. It can be used after sex where no birth control method was used or the sex was non-consensual.

Emergency contraception is a method of preventing pregnancy which works by preventing ovulation from occurring.

This means that even if there is sperm present in the woman’s reproductive system, there will be no “egg” to fertilise. This also means that if the woman is already pregnant, it’s not going to change anything or harm the baby.

Studies have shown that the different methods of emergency contraception are between 75-99% effective at preventing pregnancy.

There are two main types: EC pills and the copper IUD. Both methods can be used up to 5 days after unprotected sex, but ideally within 72 hours.

There are a few different pill regimens to choose from.

The first, and the most recommended option due to having fewer side effects, are the progesterone-only pills. These pills contain levonorgestrel, sold under the names: Escapelle, Plan B, Norlevo. Another option is a pill containing ulipristal acetate, sold under the name Ella or EllaOne.

The other regimen available includes taking a number of pills with both oestrogen and progesterone. This means that, depending on the strength of the hormones in the pills, you could theoretically use your own birth control pills that you have taken in the past without having to go out and get something else. This does mean that you would need to start a completely new pack of pills afterwards, to start a new cycle again. This method is known as the Yuzpe Method. This method is less effective, but in certain circumstances, it may be the only viable option for some women. For example: teenagers; those with financial constraints; or those with limited access to healthcare.

This method is more likely to have side effects such as: nausea and vomiting, dizziness, headaches, lower abdominal pain and a heavier menstruation. If you use this method, or any pill method, and you start vomiting soon after, you will have to take medication to stop the vomiting, then take the EC pills again otherwise they wont be effective.

The other type of EC is the copper IUD. This is the most effective method and can be inserted at any time within 5 days of unprotected sex. This needs to be done by a qualified health professional.

The copper IUD works by preventing fertilisation from taking place. The Cu ions in the IUD disrupt sperm function and prevent them from fertilising the “egg”. If fertilisation has already taken place, the Cu ions can help again by preventing implantation into the lining of the uterus.

Remember: If you miss the 5 day mark then it is too late for any method to be effective!

Make sure you don’t waste any time and take your EC as soon as possible, the sooner the better!

Now that we’ve covered the basics of what emergency contraceptives are and how they work, we can address our initial question, “Will taking emergency contraceptive pills affect my fertility and reduce the chance of me getting pregnant in the future?”

The answer is: absolutely not!

As discussed above, emergency contraception disrupts the normal menstrual cycle by preventing ovulation from taking place – only for that cycle in particular. So if you used the “Plan B” pill within 72 hours of unprotected sex, the hormones would disrupt your natural cycle, and prevent the ovulation phase of the menstrual cycle. You could then immediately start taking a new pack of your normal birth control pills the next day, restarting your cycle again. Your menstrual cycle would then proceed as it usually does, just like it did before you took “Plan B”.

Emergency contraception does not cause any harm to your ovaries, your uterus or your fertility. It is safe.

You are now free to have children only IF and WHEN you want to!
