From the information provided, it appears your ultrasound results are relatively benign. You have multiple uterine fibroids but your endometrium appears benign. Your ovaries are normal for an ovulating female and there are no suspicious masses in your uterus.
Pelvic pain is a common presentation for uterine fibroids. This is because fibroids either press on sensitive structures in the pelvis or outgrow their blood supply and start to involute (the tissue dies because of insufficient blood supply). You have an appointment with your doctor next month at which you can discuss options for treating your fibroids such as fibroidectomy (removing the fibroids) or hysterectomy (removing the uterus).
There is no harm waiting until your appointment next month unless, of course, you start experiencing a change or increase in symptoms such as increased abdominal pain or pressure, vaginal bleeding, nausea, vomiting, fever, or sudden increase in abdominal girth. In those cases, you should seek immediate medical attention.
