How should you take birth control pills and is it possible to get pregnant while taking them:
A doctor's explanation of how birth control pills work:
According to doctors and the media, oral contraceptives are the most reliable protection against pregnancy. But birth control pills are not an extremely reliable means, and pregnancy can occur in some cases. Such situations are described in the instructions for contraceptives, but not all women study such an extensive amount of information.
Many people believe that negative factor– this is the use of the “wrong” oral contraceptive with a low content of hormones. However, in practice it turns out that almost all modern contraceptives have a similar composition of components. For young girls, the doctor prescribes low-dose medications that contain 0.02 mg of ethinyl estradiol. This amount of substance is enough to block ovulation.
When taking contraceptives that contain estrogen, the formation of dominant follicle in the ovary, and the woman becomes temporarily infertile. There are tablets of a different principle of action that do not guarantee 100% blocking of the onset of ovulation, but thicken cervical mucus to a consistency that does not allow sperm to pass out of the vagina. Such tablets (popularly called mini-pills) are inferior combination tablets in reliability, however side effects less on their part.
Taking the mini-pill does not reduce production breast milk, so these tablets are prescribed even to nursing mothers. Reception is less likely to provoke the development of problems in cardiovascular system, which allows them to be prescribed to women over 35 years of age ( heavy smokers smoking more than 10 cigarettes per day). Since there is still a small risk of becoming pregnant, doctors recommend birth control pills to women who have reduced fertility, which is typical for nursing mothers and women over 35.
The effectiveness of birth control pills decreases if a woman experiences regular bleeding and intermenstrual discharge. During the first 3 months of taking medications, the body gets used to them, so such phenomena are considered normal. A high risk of becoming pregnant while taking the pills occurs in the first 7-14 days from the moment of taking the pills, if you do not take additional protection. These restrictions are typical only for the first cycle; they are not present in subsequent cycles.
What can happen if a woman becomes pregnant while taking contraceptives? Taking the pills for the first 3-4 weeks does not affect the fetus and is not a reason for abortion. But if between pills (week break) menstrual bleeding doesn't open, don't rush to open it next package– make sure you are not pregnant.
