Dark Red Spotting After Your Period: What to Know

Dark red spotting after your period is often older blood leaving the uterus, but bleeding between periods can also result from hormonal changes, contraception, infection, polyps, fibroids, or changes in the cervix or womb. The colour alone cannot identify the cause. Note when it started, how long it lasted, how much blood you saw, and whether pain, unusual discharge, fever, dizziness, or pregnancy could be involved.

Blood can look dark red or brown when it takes longer to leave the uterus and becomes less fresh. A small amount may appear as the last part of a period, after a change in hormonal contraception, or around an irregular cycle. Spotting can also occur after sex when the vaginal or cervical tissue is irritated.

An infection such as Chlamydia can cause bleeding between periods, particularly when there is pelvic discomfort, pain during sex, or unusual discharge. Endometrial Polyps and Uterine Fibroids can also contribute to irregular bleeding. Cervical Dysplasia, Cervical Cancer, and Womb Cancer are less common explanations, but bleeding that keeps returning or happens after menopause needs assessment rather than being explained by colour alone.

If the spotting is light and you feel well, keep a simple record of its timing, appearance, amount, cycle pattern, medicines, contraception, and associated symptoms. Take a pregnancy test if pregnancy is possible. Avoid vaginal douching, and arrange a routine appointment if the bleeding recurs, follows sex repeatedly, lasts beyond your expected cycle pattern, or is new for you.

A clinician may ask about your menstrual history and sexual health and may offer a pregnancy test, examination, infection testing, cervical screening when appropriate, or an ultrasound. The right evaluation depends on your age, pregnancy possibility, medicines, contraception, and examination findings.

Seek urgent medical help for heavy or rapidly increasing bleeding, fainting, marked dizziness, severe or one-sided pelvic pain, shoulder-tip pain, or bleeding during a possible pregnancy. These symptoms can need prompt assessment, including for pregnancy-related problems.

Arrange prompt medical advice if spotting comes with fever, worsening pelvic pain, foul-smelling discharge, pain during sex, or bleeding after menopause. Even without these warning signs, recurring bleeding between periods should be checked so that infection, a structural cause, or a cervical or womb problem can be considered.

Ask what might explain the timing and colour of the spotting, whether you need a pregnancy or infection test, and whether your contraception or medicines could be contributing. You can also ask which changes should prompt urgent care, whether an examination or ultrasound is appropriate, and when to arrange follow-up if the spotting stops.
