A woman cannot get pregnant if she doesn't ovulate because there is no egg to be fertilized. The Pill also works by thickening the mucus around the cervix, which makes it difficult for sperm to enter the uterus and reach any eggs that may have been released. The hormones in the Pill can also sometimes affect the lining of the uterus, making it difficult for an egg to attach to the wall of the uterus. Most combination pills come in either a day pack or a day pack.
One hormone pill is taken each day at about the same time for 21 days. Depending on your pack, you will either stop taking birth control pills for 7 days as in the day pack or you will take a pill that contains no hormones for 7 days the day pack.
A woman has her period when she stops taking the pills that contain hormones. Some women prefer the day pack because it helps them stay in the habit of taking a pill every day. There is also a type of combination pill that decreases the frequency of a woman's period by supplying a hormone pill for 12 weeks and then inactive pills for 7 days. This decreases the number of periods to one every 3 months instead of one every month. Another kind of pill that may change the number of monthly periods is the low-dose progesterone pill, sometimes called the mini-pill.
This type of birth control pill differs from the other pills in that it only contains one type of hormone — progesterone — rather than a combination of estrogen and progesterone. It works by changing the cervical mucus and the lining of the uterus, and sometimes by affecting ovulation as well. The mini-pill may be slightly less effective at preventing pregnancy than combination pills. The mini-pill is taken every day without a break.
A girl who is taking it might have no period at all or she may have irregular periods. For the minipill to work, it must be taken at the same time every day, without missing any doses.
Any type of birth control pill works best when it is taken every single day at the same time of day, regardless of whether a girl is going to have sex. However, low-dose pills may result in more breakthrough bleeding — bleeding or spotting between periods — than higher dose pills. Combination birth control pills prevent your ovaries from releasing an egg. They also slow an egg's progress through the fallopian tubes, thicken cervical mucus and thin the lining of the uterus endometrium.
All of these actions help keep sperm from joining the egg. The minipill slows an egg's progress through the fallopian tubes, thickens cervical mucus and thins the endometrium — all of which help prevent sperm from reaching the egg.
The minipill sometimes also suppresses ovulation. Your doctor will ask about your medical history and any medications you take to determine which birth control pill is right for you.
