How long does your period take to come on the pill?

I take the pill and misused it a couple times last month. I didn’t have actual sex and no semen got into my vagina through other kinds of sex, yet my period is nowhere to be found. We are going on day 4-5 of my placebo pills and there is no period in sight. I only got fingered last month and did some light grinding I’m freaking out ladies!!!
