###Human: Took I-pill after one hour of unprotected sex. Will periods be regular? ###Assistant: Hi. Your partner has taken the I-pill after one hour of sex. This rules out the chance of pregnancy in all respect. So, please relax. You have nothing to worry for now. But, you should ask her to start regular pills like Femilon (Ethinyl estradiol and Desogestrel) or Novelon from first day of her next cycle. This should be continued for 21 days and new pack to be restarted after a gap of seven days. This is an excellent form of contraception. Now, she may have some form of bleeding within two to three days. Do not panic. This is normal as a reaction of the I-pill. Her next cycle will be delayed also. This is also normal. Just ask her to start the pill from then. Meanwhile, you use condom for protection as you cannot repeat I-pill so often. Contraceptive guidelines.
