Bleeding between periods
Bleeding between periods is known as inter-menstrual bleeding. It is quite common, and if you experience just a single episode you need not be overly concerned.
Common causes are medications containing oral hormones (estrogen, progestogen) such as in contraceptive agents and other oral hormonal therapies.
Ectropion, endometriosis, and polycystic ovarian syndrome (PCOS) can also be associated with inter-menstrual bleeding.
Persistent inter-menstrual bleeding may be caused by genital tract infections, polyps within the uterus or cervix, and rarely cancer of the cervix.
What to do
If you have persistent intermenstrual bleeding, you should see your GP. First-step investigations may include an examination, pap smear, or vaginal ultrasound scan.
