Scientists claim that getting pregnant by taking only birth control pills is impossible. This requires also contact with a man, but in this case, oral contraceptives are the most reliable protection against pregnancy. So, at least, approves advertising and a number of medical workers.
However, there are situations in which you can get pregnant, even using birth control pills. This, by the way, is also evidenced by the instructions to contraceptives, which have not been adequately studied by the majority of women so far.
And here it's not a "wrong" selection of an oral contraceptive, in which "not the same" concentration of hormones, because now they produce funds that differ little in composition, which has been tested and optimized. To block the ovulation of young girls sufficiently low-dosage means, in which the content of ethinyl estradiol is 002 mg.
The use of contraceptives in which estrogen is included does not allow the dominant follicle to form in the ovary, that is, the female body temporarily becomes barren.
How do contraceptives work?
However, there are tablets and other actions that can not give a full guarantee of blocking ovulation. They strongly thicken the cervical mucus thickening, preventing the progress of spermatozoa. Such tablets are called mini-pili, and their reliability is less than that of combined tablets, however, they have fewer side effects. In particular, mini-pills do not cause a decrease in the amount of breast milk, so they are advised to use breast-feeding women. In addition, with these pills, there are fewer effects that adversely affect the cardiovascular system, and doctors are trying to prescribe them to women who are already somewhere in their thirty-five years, especially if they smoke more than ten cigarettes a day. Since there is some risk of becoming pregnant, when using contraceptives of this type, doctors are advised to use mini-pills only on strict indications, to women with reduced fertility. Fertility, this is the ability of the sexually mature organism to produce offspring, which is typical of nursing women and women after thirty-five years.
You should carefully read the instructions to the drugs, and be aware that these drugs should be taken at the same time. When more than twelve hours late, the contraceptive effect is reduced. That is, it is possible that the tablets are taken (but with delay), and the pregnancy is still there.
There is another vague option when a woman has less vomiting than three hours after using the drug. It is now necessary to use one more pill, because the first is not completely absorbed by the body. The same applies to frequent diarrhea. And in general, if a woman has a weak stomach or intestine, it is better to refuse tablets, but use a vaginal ring "Ring", or a special plaster.
Contraceptive pills and other drugs
When the contraceptive pills interact with other medications their reliability decreases. The same applies to a number of traditional medicine. In most cases, antibiotics are responsible for unsuccessful contraception, and St. John's wort is among the medicinal herbs, and its effect is noticeable even after a fortnight after the course is over. If you decide to use birth control pills, do not take any self-medication. If you are sick and the doctor has prescribed any medications, tell him that you are using this method of contraception. If you really need to take medication, use barrier barrier for the period of treatment. It can be a condom, or a vaginal cap. Possible and chemical contraception in the form of spermicides. When you have a suspicion that at the moment there is a risk of reducing the contraceptive effect should also be.
Effectiveness of drugs is reduced, with intermenstrual bleeding and discharge. In addition, when taking birth control pills, you can get pregnant if you do not use additional remedies in the first week of two contraceptive use. Then there are no such restrictions.
