Did Emergency Contraception Make My Period Come Early?

Dear Did Emergency Contraception Make My Period Come Early?,

I took an emergency contraceptive about 2 and a half weeks ago after my boyfriend thought we might have had an accident. I took a pregnancy test last week and it came out negative. About 5 days ago (10 days after I took the ecp) I got my period but it was a few weeks early (I get my period once every 8 weeks) and I have no idea what's going on! Is it a side-effect of the pill? Or am I pregnant? Could it be implantation bleeding? I really need help I have no idea what to do right now. Please help!! :(


Dear Did Emergency Contraception Make My Period Come Early?,

After you take emergency contraception (EC) it is normal for your next period to different than it is usually is. It may come earlier or later than it normally does. It is also possible for it to be heavier, lighter, more spotty or the same as usual. So the fact that you got your period early could definitely be caused by taking EC. And since you did get your period, FX cannot imagine you are pregnant.

If someone who has taken EC does not have their period within 3 weeks of taking EC, or has symptoms of pregnancy (such as frequent urination, headaches, inexplicable fatigue, a missed period, nausea, or sore or enlarged breasts), that person should take a pregnancy test and/or schedule an appointment with their doctor.

FX cannot make any definitive diagnoses about the situation, so if you continue to have concerns you should meet with your doctor. If you don't have a doctor and live in northern New Jersey, you can call the Adolescent/Young Adult Center for Health at 973-971-5199 for an appointment with an adolescent medicine specialist or contact your local teen health center or Planned Parenthood. You can also contact your insurance company for a list of in-network providers.
