Considerations

It takes discipline

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?

You want predictable periods

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.

Skipping periods

Some pills allow you to skip your period altogether, which is totally safe.

Smokers over 35, beware

For those over 35 years old, smoking while on the pill increases the risk of certain side effects.

The pregnancy question

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.
