why is a back up method of birth control necessary, if you miss two pills in a row.?

Answer 1

Seriously?

Do you want to get pregnant?

It's necessary because if you don't take the pill daily, you're not being protected against pregnancy.

Answer 2

Because for every pill you miss, your chance of pregnant jumps up 7%. So you had a 1% chance of becoming pregnant before missing any pills. Not that you've missed 2 you have a 15% chance. Doesn't sound all that high, until you're actually part of the 15% that gets pregnant. Each pill stays in your system and prevents pregnancy for about 24 hours. You go longer than 24 hours without taking one, you leave yourself unproteced. You don't take pills, you have sex, you get a baby. Simple.

Answer 3

Combination pills usually work by preventing a woman's ovaries from releasing eggs (ovulation). They also thicken the cervical mucus, which keeps sperm from joining with an egg. Progestin-only pills usually work by thickening the cervical mucus. Less often, they prevent ovulation.
The hormones in combination and progestin-only pills also thin the lining of the uterus. In theory, this could prevent pregnancy by interfering with implantation of a fertilized egg.
If you take the pill every day it maintains the level of hormone that is needed to prevent pregnancy. You can find all of this information on this website:
