Doctor

A:   Emergency contraceptive pills are the form of birth control that are to be taken within 72 hours of unprotected intercourse. The side effect of these pills is that you may experience early onset or late onset of periods, spotting etc. These pills are not recommended as a primary form of contraception.
Generally the morning after pills do not affect the subsequent cycle. Strenuous physical exercise as you rightly mentioned seems like a more likely cause of your delayed period. If you do not get your periods soon, it would be prudent to visit a doctor or clinic for an evaluation. They will most likely prescribe you with progestin hormone containing tablets to induce a withdrawal bleeding. You could also use that opportunity to discuss alternative contraceptive methods such as cyclical combined pill which will also help to regularise your cycles.
