However, symptoms such as irregular menstrual bleeding, abdominal swelling, painful menstrual period may be signs of various diseases. Women should follow the changes they experience and consult a specialist in unusual situations. If you are of fertile age and a week or more has passed before an expected menstrual cycle begins, you may be pregnant. However, this symptom can be misleading if you have an irregular menstrual cycle. The health of women's reproductive organs, the problems and diseases that may arise related to it are directly within the scope of a gynecology.
