Mild bleeding and lower abdominal pain without menstruation for a week can have several possible causes. It may occur due to hormonal imbalance, ovulation spotting, stress, or recent changes in birth control pills. Other possibilities include early pregnancy, implantation bleeding, uterine fibroids, cervical or vaginal infections, endometrial changes, or thyroid-related issues. In some cases, minor bleeding can also happen after intercourse or pelvic inflammation. Since the symptoms have persisted for a week, it's essential to consult a gynaecologist for an accurate diagnosis. The doctor may suggest a pelvic examination, ultrasound, and blood tests to determine the cause and provide suitable treatment. Avoid taking any medication on your own, and keep a record of your bleeding pattern to share during your consultation.
