What should you know about emergency contraception for overweight?

Emergency contraception is time-sensitive, and body size can be one factor in choosing between available options. The pharmacist or clinician also needs to know when unprotected sex happened, where you are in your cycle, which medicines you take, and whether you need ongoing contraception. Do not assume that an online calculator can select the right option for you.

Seek advice promptly and give accurate information about your health, medicines, allergies, and cycle. Take the recommended product exactly as directed. If you vomit soon after taking it, contact the pharmacist because another dose or a different plan may be needed. Use condoms or avoid sex until your regular contraception is effective, since emergency contraception does not provide continuing protection.

Arrange advice if your period is late, much lighter than expected, or otherwise unusual, and test for pregnancy when advised. Seek urgent care for severe abdominal pain, fainting, or heavy bleeding, particularly if pregnancy is possible. Ask for help as well if you take medicines that may interact with levonorgestrel.

Which emergency option fits my body size, cycle timing, and medicines? What should I do if I vomit? When should I test for pregnancy, and what regular contraception can I start?
