You may need some antinausea medicine. Watch for warning signs for the next couple of weeks. Your next period may start earlier or later than usual. If your period doesn't start within 4 weeks, see your clinician for an exam and pregnancy test. If you think that you may be pregnant, see your clinician at once, whether or not you plan to continue the pregnancy.
Ectopic pregnancy is a medical emergency.
As soon as you possibly can, begin using a method of birth control you will be able to use on an ongoing basis. ECP's are meant for one-time, emergency protection. They are not as effective as other forms of birth control. If you want to resume use of birth control pills after taking ECPs, consult your clinician. Protect yourself against AIDS and other sexually transmitted diseases as well as against pregnancy.
