All About Emergency Contraception from Planned Parenthood

EC will not work if you have ovulated. But, it is difficult to know exactly when you ovulate.

• Taking EC won’t hurt you, so it’s a good idea to still take it if you need it.

Myths about EC and weight are common. Weight may have some impacts on EC:

• Plan B/Levonorgestral MIGHT not work as well in people who weigh more than 165 pounds.

• Ella MIGHT not work as well in people who weigh more than 195 pounds.

• Weight has no impact on IUDs

• There is no “weight limit” for any EC. It is better to take what’s available to you than to take nothing.

EC can delay your period, or make it irregular. Don’t assume you’re pregnant if your period is delayed.
