When taking the birth control pill does it have to be at the exact same minute everyday, as in at 8:00 everydayto be effective or can it be in the same hour/half hour. I haven't taken it at the exact same time since I started it but it has been in the same hour and I haven't missed a day.  Will it still be effective and can I start taking it at the same time now to make it effective? It's my first time on it so I'm a little confused on the situation.
