Menstrual periods can be unpredictable which vary in length and timing. While normal periods vary in length and timing, spotting between periods could be a sign of a health condition that needs follow-up. Some of these causes are harmless but some of them are quite serious. I would strongly urge you to make an appointment with your OB/GYN any time you have bleeding or spotting from an unknown cause when it is not your period. That being said, spotting between periods is the source of many conditions that come into play. It can be a normal response to many lifestyle factors. Everything from birth control
pills to vaginal contraceptive rings or intrauterine contraceptive devices can cause spotting as your body adjusts to the hormone levels. Stress can affect your hormonal levels and consequently your menstruation cycle that lead to spotting between periods. Ovulation can cause mid-cycle bleeding. It is also a sign of early pregnancy or perimenopause. If you are pregnant you need to consult your doctor
right away because this can sometimes be a sign of an ectopic pregnancy, which is a medical emergency or a miscarriage. Your doctor can also help you rule out other serious health conditions such as sexually transmitted infections (chlamydia and gonorrhea), uterine fibroids, hyperthyroidism, pelvic inflammatory disease, endometriosis
, polycystic ovary syndrome, polyps, and cancer of the cervix, uterus, ovaries, or vagina.
