Hello, yes emergency contraceptive pills causes bleeding (you may bleed as soon as 4hrs of taking them, or anytime mostly common till a week). You may bleed heavily then normal, don't worry it will stop by itself, your next period may delay, your regular periods date may change. Please avoid frequent taking of ECP 's, condom is better option to avoid pregnancy.
