Yes: Having to use emergency contraception is always a cause for concern. It means that something unplanned happened, or that planning was possible but not done. In either case, there is enough concern to try to figure out a way to never need emergency contraception again. Fortunately, the medication works very well when taken on the first day.

End of period : This just represents the end of your period. The fact that you had sex then is coincidental. It sounds to me like you are worried about getting pregnant. Please use condoms until you can see a doctor to start an effective birth control method.

Slim chance pregnant: While there is a slim chance you are pregnant, irregular periods and cramping are common and have many causes. I advise an examination by your gynecologist.
