Biological or hormonal method
It involves the use of drugs, which are a mixture of sex hormones (estrogens and gestagens, so-called progestins), strictly according to the schemes specified in the appendix to the medicine. Some women may experience side effects in the form of weight gain, tenderness and engorgement of the mammary glands, nausea, headache, spotting spotting. Usually, after 1-3 months, these symptoms disappear, but still about 15% of women are forced to abandon hormones. Absolute contraindications to their use are: past and current thrombophlebitis, varicose veins of the lower extremities, liver disease, all types of tumors of any localization, diabetes, asthma, obesity, allergies. The duration of use of hormonal contraceptives should not be more than one year, after which you should take a break for 3-4 months. It is known that pregnancy occurs especially quickly after stopping hormones (withdrawal effect), therefore, at this time other contraceptive measures should be observed especially carefully and meticulously. Biological contraceptives do not have any harmful effect on subsequent pregnancy and the fetus.
