What Are the Common Causes of Black Period Blood?

  3. Hormones
    Hormonal changes can affect menstruation in a variety of ways, affecting the process in terms of regularity, amount of bleeding and total duration.
  4. Retained blood
    If blood stays for some time in uterus and vagina before being released, it will be black in appearance as well. But unless other unusual symptoms arise it should not be worrying.
  5. Some health problems
    Having some health problems such as fibroids or polycystic ovaries can cause bad period patterns. However, it is the dark blood that actually does not allow to understand what is wrong with the body.

Frequently Asked Questions

Q.1 Can those diagnosed with PCOS experience black blood on their period?

    Q.2 Is black blood an indication of an infection?

      Ans. Not always. Most of the time, old blood is to blame. Black discharge with a bad odor can sometimes also point to an infection and requires medical attention.

      Q.3 Could pregnancy lead to the presence of black blood?

        Ans. Pregnancy does not lead to a true menstrual cycle. However, it can cause bleeding, which may appear brown or black. If you suspect you may be pregnant and have unusual bleeding, then go see a doctor.
