Given that the effectiveness of the drug depends on how quickly the woman takes it, it is not necessary to go to the doctor. But, if you have unprotected intercourse and you decide to use emergency contraception, be sure to read the instructions carefully. This is mandatory, as there may be contraindications.
Now about the consultation after the reception. Women who constantly take oral contraceptives should visit a gynecologist once a year and do tests, because these drugs contain estrogen, which can slightly increase blood clotting. There is no estrogen in emergency contraceptives (only progestogen), so blood clotting does not suffer, tests are not needed.
Do not be alarmed if after taking the drug you have two monthly periods. It often happens: a menstrual-like reaction occurs (sometimes prolonged - 10 days), and then normal periods follow. If nothing else unusual happens, a doctor's consultation is not required.
However, if you are not using any reliable permanent method of contraception, still contact your gynecologist for help in choosing.
