How long will unwanted 72 disturb the periods ?
Patient: 1. Last period date 10th feb to 15 feb. Had unprotected sex on 21st feb afternoon. and. took unwanted 72 pill  after 2 hours. 3 Is this pill work for my wife. autual her next periods date 10 march but periods came on 6/03/14  and surprised  is that periods finished after 2 days its never happening before.So she is afraid of pregnancy. How long the periods will get disturbed because of this Pill. Doctor: Hi ,  Having menstrual discharge in between 20-35 days is completely normal .So last menses came after 25 days is absolutely normal .  When menstruation occurs there is sloughing off of uterine wall hence no implantation and pregnancy cannot sustain . As she had menstruation 17days following unprotected sex (again had progestin only pill 2Hr later) so negligible chance of pregnancy .So don't worry everything is fine .Thanks n regards
