Do you have to wait till you start your period to start birth control pills or can you just start taking them?
Yes you have to wait until the first Sunday after (or of) your period to start taking the pill.Oh, and after starting, if you miss 3 days you have to start all over with a new packet. Health dept. is great for answering those type of questions.
The sugar pills at the end are for during your period, so I would start after, but it depends on the type of pill, ask your doctor to be sure.
Take them after you are done with your period they work best.
What did the doctor that prescribed them to you say? Start when he/she said to.
