<s>[INST] I had unprotected sex on 22nd day of ma cycle and consumed unwanted 72 within 6hrs of intercourse. 15hrs past after taking the pill but still i m not bleeding . Is it necessary to bleed after taking unwanted 72. And is there any chance of getting pregnant if i had sex on 22nd day of ma menstrual cycle?. Plzz help [/INST] Hi,  It is never necessary to have spotting after taking emergency contraceptive although it can happen . As you have taken emergency contraceptive pill within 72 hours of unprotected sex so chances of pregnancy is low .   So don't worry and Just wait for you normal menstruation to come till 35 days of your menstruation period (if doesn't then do UPT).  Hope this ll help THANKS N REGARDS </s>
