how does the pill prevent pregnancy

Dear woman ,

Contraceptive to prevent pregnancy through several mechanisms , mainly by preventing ovulation pills. If no egg is released, there is nothing to be fertilized by the sperm and the woman can not get pregnant. Most birth control pills contain synthetic forms of two female hormones , estrogen and protesting. These synthetic hormones stabilize natural hormone levels of women, and prevent estrogen peak in bicycle . Without hitting estrogen, the pituitary gland does not release other hormones that normally cause the ovaries to release mature eggs.

Specifically, in the works of the synthetic estrogen pill :

 Stop the pituitary gland to produce follicle stimulating hormone (FISH ) and aluminizing hormone ( LHS to prevent ovulation .
 Support the lining of the uterus (endometrial ) to prevent bleeding mid-cycle .

Meanwhile, the synthetic protesting is :

  Stop the pituitary to produce LHS to prevent the release of the egg .
  For the lining of the uterus inhospitable to a fertilized egg.
  Limiting the ability of sperm to fertilize the egg part .
  Thicken the cervical mucus to prevent sperm movement ( although this effect may not be the key to   prevention of pregnancy).

There are two types of hormonal birth control pills : ( 1) the combined pill containing estrogen and protesting and ( 2) the protesting-only pill ( mini-pill known as the name). Combo pills are significantly more effective than protesting-only pills and have the added advantage of less bleeding . However, some women can not tolerate estrogen and protesting pill preferred. Both pills are available in several different brands , each of which has slightly different hormonal mixtures .

These two types of hormonal contraceptives are available in other ways besides pills . The formula for the combination is also available as a patch and vaginal ring. The formula for protesting-only is also available in intramuscular shots (Depot -Prover ) , implants (Implant ) , and intrauterine devices ( IUD Miranda) .

Some women may prefer these other forms of hormonal contraception, and that can be taken less often (and therefore easier to remember ) .

While birth control pills must be taken daily , the patch is applied once a week , the vaginal ring only once a month , and intramuscular injection once every 3 months. An IUD is inserted into the uterus and can prevent pregnancy for five years or more. In the United States , hormonal pills and devices for birth control are available only by prescription. Women can ask for a GYM or women for information on the different types of contraceptive methods, including methods would be best for them personally.

If you forget the pill one day, you may have to take two pills the next day , resulting in an increase in contraceptive hormones in their body levels . For maximum protection against pregnancy and minimize side effects , choose once you are likely to remember (maybe first thing in the morning or before bed ) and take your pill at the same time every day.

Finally , birth control pills are traditionally packs of 21 or 28 pills. Both packages contain 21 active pills . An additional 7 pills in 28-pill pack are placebo pills that are not there to remind you to continue to take the pill every day and remind you when to start the next pack . If you take placebo pills or just wait 7 days to start another , breaking 7 days from hormone triggers menstrual bleeding period imitating women.
