Hello,
It is normal to have irregular or delayed periods after taking emergency
contraceptive pills like unwanted 72 due to
hormonal imbalance. If you missed your menses by seven days, get your a home urine
pregnancy test done to rule out pregnancy.
If negative you can wait for one more week for spontaneous onset of the periods. If you still do not get your periods, then it is better to do an
ultrasound of the uterus to look for other causes of delayed periods.
To get the withdrawal bleeding
Progesterone may be prescribed by your gynecologist. On the other hand, unwanted 72 is not full proof, but it is fairly effective. There are 10% chances of pregnancy even if you had taken unwanted 72 following unprotected sex.
If the pregnancy test is positive, your gynecologist will advise you the methods of termination of pregnancy, provided the pregnancy should be within seven weeks duration and it should not be an ectopic pregnancy.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Mohammed Taher Ali
