My period is 15 days late, but the pregnancy test is negative. Why is this happening, and what should I do?

Generally, "yima" refers to menstruation, and "pregnancy" means gestation. A delay in menstruation by 15 days, despite testing negative for pregnancy, may be related to early pregnancy, excessive stress, uterine adhesions, uterine fibroids, premature ovarian failure, and other factors. Relief may be achieved through general treatment, medication, or surgical treatment. If discomfort occurs, prompt medical attention is recommended. A detailed explanation is as follows:

1. Early Pregnancy

In early pregnancy, due to relatively small fluctuations in estrogen and progesterone levels and human chorionic gonadotropin (hCG) levels not yet reaching detectable levels, menstrual delay may occur while pregnancy tests remain negative. This is a normal phenomenon and generally does not require specific intervention.

2. Excessive Stress

If work or life stress is significant and mental tension persists for a long time, it may cause temporary fluctuations in the endocrine system, leading to irregular menstruation and the aforementioned symptoms. These symptoms may be relieved through activities such as listening to music, walking, or chatting.

3. Uterine Adhesions

Uterine adhesions may be related to surgical trauma, infections, and other factors. When the cervical endometrium develops lesions or injury, the cervical canal may become obstructed, affecting the discharge of menstrual blood and causing menstrual delay despite the absence of pregnancy. This may be accompanied by symptoms such as amenorrhea and abdominal pain. Prompt medical treatment according to a physician's instructions is recommended, typically involving hysteroscopic lysis of adhesions to separate the adhesion areas.

4. Uterine Fibroids

Uterine fibroids are usually associated with multiple induced abortions, infections, and other factors. These causes may lead to uterine cavity deformation, affecting endometrial shedding and causing menstrual delay. Symptoms may include abdominal masses and increased vaginal discharge. Treatment may involve medications such as mifepristone tablets, danazol capsules, or triptolide capsules, as directed by a physician.

5. Premature Ovarian Failure

Premature ovarian failure is often related to unhealthy lifestyle habits, dietary habits, and other factors. When the body experiences severe estrogen deficiency, it may cause the aforementioned symptoms, accompanied by infertility and accelerated aging. It is recommended to follow medical advice for treatment with medications such as ethinyl estradiol tablets, estradiol valerate tablets, or drospirenone-ethinyl estradiol tablets (II).

Menstrual delay is not necessarily pathological. If the symptom duration is short, there is generally no need for excessive concern. However, if the symptom persists for a prolonged period, timely medical evaluation and targeted treatment under a physician's guidance are recommended.
