Hello, I have gone through your query and understood the concern. There is no need to use an emergency contraceptive pill around the menstrual period because this is the safe period. Ovulation occurs two weeks prior to the onset of the next period and this is the fertile period. So, in the manner you have described, you cannot get pregnant and hence, there is no need to worry. Also, restrict the use of emergency contraceptive pills to once or twice a year since they have a high hormone content and hence disturb the hormone milieu of the body badly. Hope this helps.
