Using the Pill

How the Pill Works to Reduce Pregnancy

April 18, 2018

Do you know the way the pill works to prevent pregnancy? All things considered, the pill is one of the most popular of all hormonal procedures of birth control, and it’s a really effective form of contraception. Have you ever wondered just exactly what the pill does, and why it is so successful?

The Pill Should Not Get All the Attention

To be able to understand the way the pill works, we will need to backtrack, just a little bit.

To truly know how”the pill” works to prevent you from getting pregnant, it is necessary to understand that this information applies to all types of hormonal contraception — not just the birth control pill.

For the most part, all hormonal contraceptives work the same way to prevent pregnancy. It doesn’t make a large difference whether the hormonal birth control method is a mixture method (meaning that it contains both estrogen and progestin) or even if it’s a progestin-only method.

Exceptions to the Rule How the Pill Works

There’s a slight exception to the rule of thumb on how the pill works when it comes to a progestin-only contraceptives. Depo Provera, Nexplanon, progestin-only pills, the Mirena IUD, and the Skyla IUD work in the exact same way as the pill. But, the progestin-only pill simply prevents ovulation in approximately 50 percent of women. Mirena and Skyla may also stop some women from ovulating, but this isn’t the main way these IUDs function to prevent pregnancy.

So How Does the Pill Work?

There are three ways that the pill works to avoid pregnancy.

  1. The main way the pill works is by preventing a woman’s body out of ovulating during her monthly menstrual cycle. So, if the ovary doesn’t release an egg, then there is nothing there for a sperm to fertilize. The tablet (and hormonal contraception) may also make the fallopian tubes not as likely to move an egg toward the uterus.
  1. The following way that the pill and other hormonal contraception function is that they help to thicken your cervical mucus (the fluid located around the cervix/opening of the uterus). The pill makes your mucus tacky, so when sperm try to get through the cervix, this tacky mucus makes it much harder for them to float through–so it is more difficult to reach and fertilize the egg.
  2. The last way that the pill works to prevent pregnancy has to do with the uterine lining. Hormonal contraceptives may cause adjustments to the lining of the uterus. The hormones in these methods can thin out or prevent the growth of varicose veins. This can lower the possibilities that  implantation will take place.

Hormonal contraception and the pill can operate in any or all of these ways to prevent pregnancy. To be most effective, these approaches have to be used consistently and properly. Hormonal contraceptives (as a group) are between 92 percent and 99.9% effective. This means that of every 100 women using hormonal contraception, 8 may become pregnant (with average use) over the first year and less than 1 will become pregnant with perfect use.

Does the Pill Work During the Placebo Week?

This confuses a whole lot of women. First of all, what is a placebo week?

When can it be? The placebo week is a time as soon as your pill back comprises”placebo” pills (sugar pills) that contain no hormones or a small number of hormones (significantly less than the sum in the remainder of the package ) In addition, it can be the time of the cycle when you’re not taking any pills. Not all hormonal methods possess a placebo week.

  • For of a typical 28-day pack of combination birth control pills, the fourth week is the placebo week.
  • For extended cycle pills (continuous birth control) using a 91-day pack like Seasonique and LoSeasoniqueper week 13 is the placebo week.
  • To get a 21-day package, like Loestrin, the fourth week is the placebo week (there are no pills to take this week).
  • For a 24/4-day package, for example Yaz or Beyaz, the previous four days are the placebo period.
  • For the NuvaRing, you simply take the NuvaRing out following week 3 and do nothing during week 4 (which is the placebo week).
  • For the Ortho-Evra Patch, you wear a new patch weeks , 2, and 3. You don’t use the patch week 4 (which is the placebo week).

All of these birth control methods can nevertheless prevent pregnancy during the maternity week/time. And you will almost certainly have your”period” (a withdrawal bleed) during that time.

So, yes, the tablet computer still functions during this week, even though you are not taking any hormones that are active.   This usually means that you are still protected against getting pregnant if you choose to have sexual intercourse during the placebo week/time. You don’t need to use a backup birth control method if you have sex during this time period.

Bottom Line on the Birth Control Pill Works

The main point is that the pill, as well as other forms of hormonal contraception work in more than 1 way. They could prevent a woman from ovulating, they could lead to thicker cervical mucus that disrupts the passage of sperm through the cervix, and they’re able to change the lining of the uterus in ways which inhibits implantation if fertilization occurs.

The pill proceeds to work through the month, even when you’re taking placebo pills in order that additional types of contraception are not needed. Nevertheless, the pill doesn’t reduce the risk of sexually transmitted diseases, and condoms can still be a good idea for practicing safe sex.
