Hello,
Welcome to Healthcaremagic.
Thanks for your query.
I have gone through your query and understand your concern.
It is not necessary to have bleeding after taking emergency
contraceptive pills like Unwanted 72.
As you have taken the pill after 72 hours, the chance of conception is high is high as compared to the pill taken with in 72 hours.
The chance of preventing conception is as follows:
If this pill is taken within 24 hours after unprotected sex, about 95 in 100 pregnancies are prevented.
If it is taken between 25-48 hours after unprotected sex then about 85 in 100 pregnancies are prevented.
If it is taken between 49 and 72 hours after unprotected sex, then about 58 in 100 pregnancies are prevented.
It is sometimes used between 72 and 120 hours after unprotected sex but the chance of it working is much less than if it is taken within 72 hours.
As your menstrual cycle is for 25 days and your last
menstruation is on 21 st September.
You probably had menstruation on 17th october or after that. It is been one week after your expected period.
Please do Hormone
pregnancy test now and check for any positive.
It is better to consult a Gynaecologist after doing Urine pregnancy test.
Then do
Ultrasound abdomen and pelvis to rule out pregnancy.
Hope this helps.
Please reply for further queries.
Wishing you good health.
Regards,
Dr.Manjeth Kumar
