Can I get pregnant if I have irregular menstruation for a long time?

Long-term irregular menstruation may affect pregnancy, but it is not absolute. Irregular menstruation is usually related to abnormal ovulation. If ovulation function is normal, pregnancy may still occur. If there is persistent anovulation or luteal insufficiency, the probability of pregnancy may be reduced.

Irregular menstruation manifests as cycle disorders, abnormal menstrual flow or prolonged menstruation, which may be caused by polycystic ovary syndrome, thyroid dysfunction, hyperprolactinemia and other diseases. These diseases may interfere with follicular development or prevent a fertilized egg from implanting. Some patients still ovulate spontaneously despite irregular menstruation. Ultrasound monitoring can detect the formation of dominant follicles. In such cases, there is still a chance of natural conception. For obese women with polycystic ovary syndrome, weight loss can help restore ovulatory function.

Persistent anovulatory irregular menstruation may lead to infertility and is common in diseases such as premature ovarian failure and pituitary microadenoma. Long-term stimulation of the endometrium by a single estrogen without progesterone resistance may lead to endometrial hyperplasia and even malignant transformation. Such patients require hormone replacement therapy or ovulation induction treatment to resume menstrual cycles. People with insufficient luteal corpus are prone to early miscarriage even if they become pregnant, and need to supplement progesterone to maintain pregnancy.

It is recommended that patients with irregular menstruation who have fertility needs undergo basal body temperature measurement, six sex hormone tests and gynecological ultrasound to evaluate ovulation function. During pregnancy preparation, you can record your menstrual cycle and use ovulation test strips to monitor the day of ovulation. It is necessary to maintain a regular daily routine and avoid excessive dieting or strenuous exercise. Those with an excessive body mass index should control their body fat rate within the normal range. If your attempt to conceive naturally is unsuccessful, you should promptly go to the reproductive medicine department for a systematic evaluation.
