Micronor (norethindrone): Ortho micronor (norethindrone) (http://www.Drugs.Com/cdi/ortho-micronor.Html) is a progestin-only birth control pill that requires much stricter attention to timing of dose, such as you describe. Under those conditions, it is a very effective form of contraception by preventing ovulation. Some women still get normal periods while on pill but that doesn't imply they're ovulating.

You would need to miss about 5 - 7 pills to induce a period flow. A urine pregnancy test would be quicker and safer than skipping pills.
