It is possible to get pregnant with irregular menstruation. There are many causes of menstrual disorders, most of them are associated with fibroids, thin or thick endometrium, etc. Some of them can get pregnant after appropriate treatment. Irregular menstruation is the disorder of menstruation, including low menstrual flow, increased menstrual flow, etc. It is generally divided into premenstruation, midmenstruation and late menstruation, and is a common gynecological condition. If it is caused by diet, mental stress, sleep quality, medication and other factors, it is recommended to take regular rest and recuperation, which can generally recover on its own and has no major impact on pregnancy. If the problem is caused by pathological factors such as fibroids, endometriosis, ovarian cysts, etc., which lead to prolonged menstrual cycle and heavy menstruation, the cause should be clarified by gynecological ultrasound and the doctor should assess whether the ovaries can ovulate normally. If ovulation is normal, pregnancy is possible. If ovulation is impaired, ovulation promotion can also be used to help the patient get pregnant by adjusting the menstrual cycle. Patients with irregular menstruation should usually take rest, not stay up late, moderate nutrition, not over dieting to lose weight, relax, etc. If there is no serious uterine pathology, the fallopian tubes are open and the ovaries are ovulating normally. Most women can conceive naturally although they have irregular menstruation.
