###Human: Why is there no withdrawal bleeding after taking I-pill the second time? ###Assistant: Hi. Since you have taken an emergency pill within 72 hours of intercourse there is no chance of pregnancy. This could be because of hormonal changes due to the pill you have taken. So relax and do not worry. But please do not use the pill so frequently, as it is a hormonal pill and can cause hormonal changes in the body. Take care.
