There are lots of different kinds of pills on the market, and new ones come out all the time. Most kinds work by releasing hormones that keep your ovaries from releasing eggs.
You've got to remember to take your pill at the same time every day. Even on weekends. Even on vacation. So, ask yourself: How good are you with stuff like that?
If you feel comforted by getting your period every month—and not having random spotting in between—this could be a good choice for you.
Some pills allow you to skip your period altogether, which is totally safe.
For those over 35 years old, smoking while on the pill increases the risk of certain side effects.
You should be able to get pregnant just a few days after stopping the pill. So if you don't want to get pregnant right away, make sure you start using an alternate method as soon as you stop taking the pill.
