How to Prevent Pregnancy After Sex

If you’re having sex, it’s not always a guarantee that you’ll get pregnant. The morning-after pill and emergency contraception pills (ECPs) can help prevent pregnancy up to 5 days after unprotected sex, but they can’t prevent an egg from being released or implantation. You may also use these methods if your partner has an IUD or copper IUD inserted into his or her body as well:

The morning after pill

The morning after pill is not 100% effective, but it’s more effective the sooner you take it. If you’re already pregnant and you’ve been having unprotected sex with a new partner, then taking the morning-after pill will probably not work at all.

The morning-after pill can also be ineffective if taken too late in your cycle (after ovulation). It’s best to try this method as soon as possible following intercourse.

The copper IUD

An IUD is a small T-shaped device that’s inserted into the uterus by your doctor. It can be used for five to ten years, and it’s 99% effective at preventing pregnancy when it works.

There are two types of IUDs: the ParaGard® and Mirena® intrauterine system (IUS). The ParaGard® has been available since 1988, while Mirena® was approved in 2000. Each comes with its strengths and weaknesses:

  • The ParaGard® is meant to protect against pregnancy for up to 12 years; it releases copper ions into your body for this purpose. The side effects include cramps and spotting between periods; if you’re allergic to nickel or other metals found in this type of device, talk with your doctor about getting something else instead—but note that these aren’t common problems!
  • The Mirena™ provides similar protection from pregnancy as its predecessor did but also releases levonorgestrel into the uterus at a slightly lower dose than before (which means less cramping). This makes it easier on women who have had previous surgery or difficulty getting pregnant due to other conditions such as cancer treatment drugs like chemotherapy since they won’t cause nausea during treatment anymore either—just remember not only what kind

Emergency contraception pills (ECPs)

ECPs are a type of medication that can be taken to prevent pregnancy after sexual intercourse. They work by delaying the release of an egg from the ovary and making it difficult for sperm to fertilize an egg.

To take ECPs:

  • Take one pill within 72 hours (3 days) after having unprotected sex. If you have forgotten to take your medicine, take it as soon as possible even if it’s time-sensitive and/or if you don’t think that you need emergency contraception right now (for example, because there is no way for us here at The Emergency Contraception Center to know when this happened or what happened). You should also use condoms until you finish taking all the pills in your pack!
  • Wait at least 12 hours before trying again—this gives sufficient time for this medication to work its magic! And remember: while using EC, they will most likely feel like period cramps or headaches; nothing else unusual should happen during these few days either.”

You can prevent pregnancy after having sex, but it’s not always immediate.

There are several options for emergency contraception. It’s not always immediate, and it’s not always easy to get. If you’re having sex with someone who is not your partner, there are also other options:

  • The morning after pill (Plan B) can be taken up to 72 hours after unprotected sex. It prevents pregnancy by inhibiting ovulation in women who haven’t yet ovulated.* The copper IUD (Mirena) can prevent pregnancy by releasing a hormone that thickens cervical mucus and decreases sperm count.* A condom provides an extra barrier against STIs and unplanned pregnancies but may not protect against all STIs or prevent all types of infections (e.g., herpes).


preventing pregnancy after sex is possible, but it’s not always immediate. If you’re worried about this happening to me, I would recommend talking to someone about it who knows more about birth control options than I did.
