Professional Assessment: Given the patient's age and symptoms, the primary differential diagnoses include dysfunctional uterine bleeding (DUB), hormonal imbalance, and anovulatory cycles, which are common in young women. While the pelvic ultrasound shows normal uterine size (7.1cm x 4.1cm) and endometrial thickness (11.0mm), with unremarkable adnexa and surrounding structures, the irregular bleeding pattern suggests a potential hormonal dysregulation. Additional testing should include complete blood count, thyroid function tests, prolactin levels, and hormonal panel (FSH, LH, estradiol) to rule out underlying endocrine disorders, particularly given the patient's young age and the sudden change in menstrual pattern. The normal ultrasound findings rule out structural causes (such as fibroids or polyps), pointing more strongly toward a functional/hormonal etiology that requires further endocrine workup.
Based on the clinical presentation and ultrasound findings, here is my urgency assessment: Urgency Level: MODERATE The patient's irregular bleeding pattern and heavy menstruation, despite normal pelvic ultrasound findings, warrants medical evaluation within 1-2 weeks. While the imaging shows no acute structural abnormalities, the prolonged heavy bleeding could lead to anemia and requires hormonal workup and management. Red flags would include severe heavy bleeding (soaking through pad/tampon every hour), severe pain, dizziness, or shortness of breath - these symptoms would elevate this to an immediate ER visit, but based on current presentation, scheduled follow-up with a gynecologist is appropriate.
Based on the symptoms of irregular menstruation and heavy bleeding (menorrhagia), with normal pelvic ultrasound findings, I recommend starting with combined oral contraceptive pills to regulate your menstrual cycle and reduce heavy bleeding. Additionally, take iron supplements (325mg ferrous sulfate daily) to prevent anemia from the prolonged bleeding, and use NSAIDs like ibuprofen (400mg every 6-8 hours during heavy bleeding days) to help reduce flow and manage any associated pain.
