###Human: What are the consequences of taking two Postinor pills three times in a cycle? ###Assistant: Hi. I can understand your concern. Emergency contraceptive pills prevent pregnancy by interfering with the normal cycle and preventing ovulation, fertilization, implantation, etc., and in return gives withdrawal bleed within 1 to 2 weeks. As soon your reproductive system got ready for bleeding, you took another emergency pill like this three times, the cycle would have got disturbed. That is why you are not getting proper menstrual bleeding. Now no need to have any hormonal treatment. Let the body can have some time to return to normal, regular pace. In between, you might have bleeding irregular, spotting, etc. Have a healthy diet, mild exercise, and walk and nice recreational activities to come back to normal pace.
