Health expert warns you need to see doctor if period blood is certain colour

A health expert has advised women and those who menstruate on what to look out for during their cycle.

It's entirely normal to experience changes in colour and texture of blood when on your period, but when should it be a cause for concern?

Health expert and founder of leading gynaecological health company and virtual health clinic, Valentina Milanova, has since lent her expertise on the matter and shared what each colour or texture variation means.

Bright red

Milanova tells The Mirror that this occurs when the blood has just left your uterus and it's common during your 'heaviest' flow days.

Dark red to brown or black

Milanova advises that older blood has more time to oxidise and will 'appear darker in colour' - though this can also happen at the start of your period.

Pinkish or orange

This occurs when your blood mixes with cervical fluid or if there is a lighter flow.

Blood clots

Blood clots can range in size from that of a 10p coin to the size of a gold ball, she says.

According to MedicalNewsToday, these clots are a result of the endometrial cells that line the uterus being stripped away and as it exits the body, it coagulates to stop the uterine lining from continuously bleeding.

And Milanova assures that they are normal - especially on days of heavier flow.

She added: "Period blood can sometimes have a stringy or jelly-like texture due to the presence of endometrial tissue and cervical mucus."

When should you see a doctor?

Milanova said: "While variations in colour and texture are common, there are some instances where you should seek medical attention."

Grey or greenish discharge

This could be sign of infection, such as bacterial vaginosis or trichomoniasis.

Large clots

If you're experiencing clots bigger than a golf ball or 'excessive clotting that soaks through pads or tampons', then you should also seek medical attention.

Foul odour

Similar to greenish or grey discharge, this could also 'indicate an infection', with Milanova urging women to note any significant changes. These changes can include sudden heavy bleeding or prolonged periods, in the event of needing to see a doctor.

She says: "I recommend consulting a healthcare provider if you experience any of the concerning colours, textures, or symptoms mentioned above.

"Additionally, if your periods become significantly heavier, longer, or more painful than usual, if you experience bleeding between periods or after sex, or if you miss three or more consecutive periods, it is advisable to seek medical advice."

Milanova went on to say that changes can sometimes be 'indicative' of conditions such as endometriosis, fibroids or some forms of cancer.

Ultimately, if you have any concerns with regards to your period, you should always seek the advice of a medical professional.
