Hello, you should expect the bleeding from 4hours of taking tablet or upto a week or more. I pill are high dose progesterone pills which acts by shedding endometrium (as bleeding) making uterus not suitable for implantation of fertilized ovum. As a side effect your next period as delay, periods date may change from now on. Next time please consider condom contraceptive, which has no side effects.
