If you are on a mini pill, each pack will contain 28 pills. If you are on a combined pill, each pack will most likely contain 21 pills and you need to take a seven day break after each pack. It is also possible to start using the pill at a different point during your cycle. However, if you do not start taking it on the first day of your period you will need to use additional contraception for seven days. When you restart taking the pill after a break, you need to start the same way.
