Irregular menstruation can lead to conception. However, relatively speaking, the chances of conception are reduced, and if a normal mature egg can be discharged, normal conception can be achieved. Irregular menstruation is a clinical manifestation that can be caused by a variety of reasons, categorized as abnormal menstrual flow, prolonged menstrual period, shortened menstrual cycle, prolonged cycle, dysmenorrhea and so on. If the irregular menstruation is caused by living environment, dietary habits, late night, etc., it has little effect on pregnancy. However, if the menstrual irregularity is caused by diseases such as endometrium, cervical polyposis, adenomyosis, fibroids, etc., it is likely to affect conception. If you want to conceive after experiencing irregular menstruation, you can first undergo a systematic examination to assess ovarian function, follicle quality, tubal patency and sex hormone levels. If they are all normal, you can do follicle monitoring, and plan to have intercourse when you have strong positives, which will improve your conception rate and get you pregnant as soon as possible. Therefore, irregular menstruation should go to the gynecologist in time to find out the cause of the disease. If the irregular menstruation is caused by the disease, it should be treated actively so as not to affect the conception.
