we did not have intercourse, but I took an i pill, is that the reason why my period is late

Hi

I was supposed to get my period on the 31st of this month!On the same day my partner and I got intimate!we did not have intercourse!But his penis rubbed against my vulva!we pulled back soon!

Just to be on the safer side I took an I pill within the next 24hrs...I haven't got my period yet!I'm really worried!I'm late by 5 days

Please help!
