When taking birth controls, it is required to visit a gynecologist at least once a year. In the presence of risk factors (age over thirty-five years, smoking, chronic diseases, etc.) monitoring is required every six months.
An urgent visit is needed when severe pain in the calf muscles, chest pain, coughing with bloody sputum, severe abdominal pain, sudden visual impairment, or the onset of yellowing of the skin occur. Also, a visit to the doctor is required if when using a contraceptive you developed elevated blood pressure, migraine, or a significant weight gain.
