How do birth control pills actually work in the woman's body?

My girlfriend says that she can stop her period for a while just by taking these pills, so i want to know how they work.How do birth control pills actually work in the woman's body?
Birth control pills, contain hormones that suppress ovulation. During ovulation an egg is released from the ovaries, without ovulation there is no egg to be fertilized and pregnancy cannot occur.





I think there are only 2 types of birth control pills -- the combined pill and the Minipill.





The combined pill contains both estrogen nd progestin, while the Minipill contains only progestin.





The progestin in the Minipill may prevent ovulation; however it may not do this reliably each month. The Minipill works further by thickening the mucous around the cervix and preventing sperm from entering the uterus. he lining of the uterus is also affected in a way that prevents fertilized eggs from implanting into the wall of the uterus. The Minipill is taken every day. You may not have a period while taking the Minipill, if you do have periods that means you are still ovulating and your risk for pregnancy occuring is greater.





Combination birth control pills come in either 21 or 28-day packs. You take one pill each day at the same time for 21 days. If you have a 21-day pack, you stop taking birth control pills for 7 days at the end of the pack. If you are taking a 28-day pack, you continue taking pills every day, the last 7 non-hormonal pills serve as a reminder to help you remember to take your pill at the same time every day. Your period will occur during the week you take the 7 reminder pills.

Birth control pills contain hormones that suppress ovulation.





You can stop your period for a while by taking these pills. Most pills come in 28 day packs--the first three weeks are active pills and the last week are placebo pills that are there in order to remind you to take the pill at the same time everyday. It is during this last week of pills that you usually get your period. However, if you skip that last week of pills you can stop from getting your period--women do this sometimes when they're going on vacation or even for the wedding and honeymoon. The maximum amount of time you can stop it is really 3 months, because after that you'll get breakthrough bleeding.
If you want a birth control pill that gives you a high level of effectiveness and a low level of hormones? These benefits and one that may provide shorter, lighter, more predictable periods.
