###Human: Other than I-pill, is there any method to prevent pregnancy followed by unprotected sex? ###Assistant: Hi. From day 1 to 10 of the period, it is a safe period. There is no chance of pregnancy as there is no ovulation happening during this period. So if you had intercourse during your safe period, there is no chance of pregnancy. Also, you say that you have followed a withdrawal method. So relax and do not worry. However, if you have a doubt then take an emergency contraceptive pill within 72 hours of intercourse. There is no chance of pregnancy. The side effects of the pills are minimal and temporary. However, if you have a doubt then get back to me. Take care.
