Negative effects of taking the pill a week longer?

It doesn’t hurt you at all. In fact, one brand, seasonale is just like regular birth control, but packaged to be taken for the whole month for 3 months in a row, so you only have 4 periods a year. They say 4 a year is the minimum before there’s any harm.

Awesome! But another question I have is once she’s off the placebos, that pack will only have two weeks. Will her body instinctively wait for the fourth week, or will the lack of birth control make it come on the third?

I’m sorry I don’t understand your question at all. Can you rephrase it? there are generally 4 weeks in one package of pills—why would there only be two weeks?

I’m not sure if this is exactly what you’re asking, but I think it’s what you’re getting at: Some women will have a period the week that they’re supposed to even though they skipped the placebos and are taking the normal pills. (I had my period anyway the first 3 months I was on seasonale, I think the package says that this is true to some extent for about 50% of women. So that’s a bummer, but it was a lighter and shorter version.

What I mean is, She will go four whole weeks without a period. The fifth week she takes the placebos from the first pack. In the next pack there is now two weeks worth of birth control and one week of placebo. When she is on the second pack, will she have her period on the third week, or will her body instinctively wait until the fourth week?

I hope that is more clear.

It is, thanks! She should skip the placebos completely. Just throw them out, and go directly to the next month’s pills. It just gets your cycles more messed up if you take them.

Ok thanks. You have no idea how much this helped!
