### output:

Hallow Dear, You have taken hasty steps after the intercourse and have landed into a stressful situation. The egg is released 14 days prior to the next menses. Egg has a life of 24 hours and the sperms are active for 72 hours. Hence, a period of about a week is a fertile window. In short, during menstrual flow, there is no egg present and hence there is no possibility of conception. So there was no necessity of any protection by Unwanted 72 pills. You have given her Unwanted 72 pill. This pill has following after effects:1. There may be some bleeding a few days after the pills. 2. The following period may get delayed by about a week or so. So there is no reason to get worried about delayed menses. Wait patiently, and she will get the menses (Provided you did not have any other incidence of unprotected intercourse during the cycle). One more word of caution : Blood is a very good medium for pathogenic organisms; hence there is a great risk of infection if you perform sexual intercourse during the bleeding phase of menstrual cycle. Please avoid it. I hope this helps you.
