Hello,
Thank you for your query at DoctorSpring.com
If the morning after pill was taken the following day, then there is no chance of pregnancy. Failure rate is 2-3 %. Also, you are on birth control, and yes time should me maintained, but if you are taking it within an hour's difference regularly, it is definitely effective.
Considering all that, you will not get pregnant.
What you have done though is ruin your cycle dates completely by taking the ipill, since you are also on birth control, your periods may get delayed by a few days.
So there is no chance of pregnancy, but your periods will be delayed.
Regards.
