Hi , How are you doing?
That bleeding is absolutely normal.
Just 1 day after the bleeding stops, that pill was not needed. The pill is same hormone produced in body in the second half of periods, so when suddenly such a high dose of the hormone is given, the thickness of inner lining of
uterus is increased, but this is a single dose of hormone, so it will not stay on, it will be shed within 7-10 days. As the lining has to completely go, it will be dark or thick blood for few days( 7-10 days).It will stop on it's own.
It is always advisable to use some other method.Emergency pills success on repeated use may not be good.They cause such bleeding which put you in a dilemma .
If No deliveries yet - Condom or better- Combined oral pills
If delivered - Copper -T is best
There an array of other methods.
Hope I cleared your query
All the best
