Intermenstrual bleeding has a number of possible causes including infections, hormone changes, ovulatory dysfunction, polyps, fibroids or other structural growths.
A detailed consultation to find out about your menstrual, sexual, past medical and family history, followed by a physical examination will guide your doctor on the investigations needed to further evaluate this unscheduled bleeding. This includes vaginal swabs, STI tests, pelvic ultrasound, blood tests such as thyroid function and hormonal profiles and other procedures to examine the uterus.
