Bleeding which happened is bcz of the earlier pill and is called withdrawal bleeding,which has disrupted the uterine lining already ,so taking another pill at this stage is not necessary,and would further lead to delay in periods.So now u probably have to wait for your due date which is anyways expected to be delayed ,u may go for a
pregnancy test if there is a delay of more than 15 days.
Next Steps
wait patiently as advised above
Health Tips
