###Human: Is it normal to miss periods after taking I-pill? ###Assistant: Hi. I can understand your concern. As she took emergency contraceptive pill within one hour, the possibility of pregnancy is less. The bleeding she got after 6 to 7 days could be withdrawal bleeding due to emergency contraceptive pill. As she disturbed natural cycle by taking pill, now it may some time for regularization of cycles. And next period may come after one month of spotting. Cramps, nausea may be due to some other causes like infection either vaginal or gastric, renal related, etc. Clinical examination and ultrasound will help in finding out the possible cause of the problem and treatment can be taken accordingly.
