:SOn the pill?
You mean the time you take it? Yes, that one time, but stick with the time you take it.
You have to take it at the same time every day and stick with that time or you'll screw your body up (hormones) and get breakthrough bleeding; not to mention risk pregnancy if you're having sex.
Yes. You want to keep taking your pill the same time everyday for it to be the most effective. If for some reason you need to change the time you are taking it, then the safest time is right after you finish your period.
