Does Taking Oralcon Delay Periods?

Hi, I started on the contraceptive pill (oralcon) this past month and I had had finished the red ones and had 2 white ones when I had sex. His condom fell off however, I was not too worried because he did not ejaculate. My period is now almost 3 days late. I am so so stressed! Some friends have said that the pill can delay your period but is that true?
