Bleeding or spotting between periods is not uncommon, but it should be checked by a doctor if it happens more than once. There are many different causes of bleeding between periods, some of which may not be anything to worry about, but others can indicate a serious underlying condition. Here are some possible causes of spotting between periods:

• Hormonal Imbalance: Estrogen and progesterone are the two hormones that regulate the menstrual cycle. If they get out of balance, it can cause spotting between periods. This can be due to dysfunctional ovaries, thyroid gland problems, or starting or stopping birth control pills.

• Infection: An infection in the vagina, cervix, or uterus can cause vaginal bleeding between periods. Some sexually transmitted infections, like chlamydia, can also cause spotting.

• Hormonal Contraceptives: Hormonal contraceptives, such as the pill, patch, or implant, can cause irregular bleeding or spotting, especially during the first few months of use. If bleeding between periods is very heavy or lasts for longer than 3 months, it may be a good idea to seek medical advice.

• Pregnancy Complications: Bleeding or spotting during pregnancy can be a sign of a miscarriage or ectopic pregnancy.

• Uterine Fibroids or Polyps: These are noncancerous growths in the uterus that can cause bleeding between periods.

• Cancer: Although rare, vaginal bleeding between periods can be a sign of cancer of the reproductive system, such as uterine cancer.

If you experience spotting between periods, its important to see a doctor for testing, diagnosis, and treatment options. Make an appointment if spotting concerns you, or if you have spotting along with symptoms such as pain in your lower abdomen, fever, or symptoms that get worse or happen more often.
