Hi, I Am Taking Microgynon 30 Contraceptive Pill And Have

Hi, I am taking microgynon 30 contraceptive pill and have taken it normally (everyday in the morning) for a whole pack and am currently in the 7 day period where I stop taking the pill. I have been sexually active with my partner and I am on the 3rd day since stopping taking the pill and still have not had any bleeding. Should I be worried? Thanks.
