Hello dear
I understand your concern
Unwanted 72 is 90-95 % effective in preventing the
pregnancy.
But it has some failure rate.
Bleeding after the pill is due to
progesterone withdrawal effect.
It is common side effect after using unwanted 72.
Unwanted 72 also causes delay in the period for 8-10 days as it cause prolongation of second phase of the cycle.
If period will delay more than 12 days then go for urine pregnancy test and or blood
HCG to confirm the pregnancy.
If you will be pregnant then still you can terminate the pregnancy by using
abortion pill under the advice of gynecologist,
Avoid
stress, take healthy diet and do regular exercise.
Hope this may help you
