Here’s Why You Need To Start Looking At Your Period Blood

Your body is trying to tell you something.
When I first started getting my period and experienced the many joys that came with each cycle — bloating, moodiness, being awash in what felt like gallons of blood — it was hard to remember that as a vital component of my ability to reproduce, my period actually had an important purpose.
As I got older though, I began to appreciate the regularity of my cycle. I felt reassured each month that my body was in sync. And in fact, it’s not only menstruating that can be an indicator of general health, but your actual period blood (and the color isn’t the only thing you should be paying attention to).
“The blood flow amount, consistency and color of the period have a lot to say about your overall health and wellness,” says Dr. Sherry A. Ross, Women’s Health Expert and Author of she-ology. The Definitive Guide to Women’s Intimate Health. Period. In fact, Dr. Sherry explains that changes in menstrual blood can often be the first indicator that something is awry with your health, pointing to medical conditions such as thyroid disease.
Sure, the topic of period blood can be a little gross, and your first impulse may be to try and ignore the flow, stopping it up with the product of your choice. But it’s worth your while to start taking a good look at what’s going on down there during your next cycle. There may be red flags (or bright red, or light brown) that you shouldn’t ignore…
“It’s important to know [that] some of the changes in the normal flow including a heavier or lighter menstrual cycle have the same list of potential causes,” says Dr. Sherry.
These causes can include lifestyle changes like stress but also medical conditions such as thyroid disorders, sexually transmitted infections (STIs), or serious illnesses like cancer or HIV. (And it’s good to keep in mind what a normal flow looks like: “The normal amount of blood loss is 4-12 teaspoons each cycle,” says Dr. Sherry.)
When your period lightens up, that can feel like a good thing (it’s nice not to be drowning in a monthly tide of crimson, right?) But there are a lot of reasons why your flow might be lighter, including birth control meds, pregnancy, or huge amounts of exercise.
“Light bleeding can be a sign of low estrogen levels caused by the birth control pill, anemia, significant weight loss or a poor diet,” says Dr. Sherry, who adds that “Watery or light bleeding could also represent a vaginal discharge which could come for a sexually transmitted infection (STI), cervical cancer or a normal pregnancy.”
Color of the blood
Blood. It’s red, right? Well, yes — but think of your period blood as more of a rainbow-type-situation.
“In the beginning of a normal period, blood tends to be bright red in color and as the bleeding comes to an end, the color will appear brown or black,” explains Dr. Sherry.
“Blood that takes longer to leave the body is a darker color red. Bleeding longer than 7 days of bright red or dark brown bleeding can be caused by a hormonal imbalance, uterine polyps, uterine fibroids, or an abnormal pregnancy.”
There’s also brown spotting, which Dr. Sherry says should be checked out by your health-care provider “to make sure you do not have a hormonal imbalance or an ovarian cyst.” One color that should definitely not be on the period blood color spectrum is gray; grayish period blood can be a sign of an infection or miscarriage.
Blood that smells bad
Menstrual blood does not smell like the latest celebrity-endorsed fragrance, nor should it. This is your body we’re talking about, not a perfume sample out of a magazine. Having said that, if your period blood smells bad, you should pay attention. And there’s a range of “bad,” from a fishy smell to just plain foul.
The causes can vary but include not changing your tampon or pad or an infection that can range from from common (like an STI) to extremely serious (such as one caused by a retained tampon). If you notice an odor, run it by your provider (but do not douche — far from being helpful, douching can actually cause infections!).
Clots or lumps
Women know that the consistency of their period blood isn’t the same as the blood that flows from, say, a cut on the finger.
“The consistency of the normal menstrual blood will be watery and stringy or fibrous,” says Dr. Sherry.
But, “if this consistency is thicker, blood clots can develop which may suggest something abnormal is happening with your hormones or within the uterus such as a polyp.”
Dr. Sherry explains that clots the size of raisins are usually not worrisome, but a clot “greater than the size of a quarter or apricot” are reasons to be concerned. And “blood clots can develop during a period but are not considered normal if persistent.”
