###Human: Will I-pill tablet work if taken two hours after the act? ###Assistant: Hello. I have gone through your history and understand your concerns. As you had I-pill, the chances of pregnancy are not there in your case. Delayed menses, if any, are due to hormonal imbalance caused by I-pill. Just wait and watch for your menses.
