In brief: BCP

They are generally effective for sure after you have completed one pack and are probably effective after you have been on it 1-2 weeks.
You should take the pills at the same time everyday, usually in the morning but that does't matter. The reason to do this is to prevent breakthrough bleeding. So, yes do the morning after pill if you do not want the possibility of pregnancy.
