What is discharge?
As taboo and temperamental as it seems, vaginal discharge plays a crucial role in maintaining vaginal health.
This unsung hero of the female reproductive system is a self-cleaning agent, carrying away dead cells and bacteria to avert infections and maintain a stable, healthy vaginal pH level.
All in a day’s work. 💪
As for what exactly constitutes this vigilant vaginal discharge? It’s a mixture of cells from your vaginal lining, bacteria, cervical mucus, and bodily fluids.
And much like your vaginal microbiome, your discharge is dynamic.
Depending on where you’re at in your menstrual cycle, its appearance can vary from clear to milky white.
Its consistency and odor can change, too (yes, it’s normal for your discharge to have some aroma).
Some women find that their discharge smells sweet, while others have grown familiar with a tangier, sour scent.
The point is that experiencing different vaginal smells and discharge is common.
There really is a wide variation in what normal is when it comes to vaginal health.
Why does my discharge smell like metal?
To decode this, it’s essential to understand that discharge can sometimes carry trace amounts of blood, especially after your period.
Blood contains iron, which, when exposed to air, can exhibit a metallic smell.
And this smell can be more prominent during your period as blood and tissue shed from the uterine lining.
So if you’re noticing vaginal smells like copper around this time, know that it’s generally nothing to worry about.
The same goes for vaginal smells like pennies.
Can discharge smell metallic before period?
Yes, it absolutely can.
Again, this is down to the presence of trace amounts of blood that might start mixing with your normal discharge.
Why does my period smell metallic?
Healthy menstrual blood smells metallic because it is rich in iron.
And once blood is exposed to air, the iron oxidizes, producing a similar smell to a freshly sharpened blade or a handful of coins.
Here’s where things get interesting: Menstrual blood is not just blood, it’s a blend of uterine tissue, mucus, bacteria, and secretions.
So, it’s entirely expected for your vaginal odors to change from cycle to cycle.
Everyone’s body is different, and you might notice variations in the smell over different days of your period as the flow and composition of the menstrual blood change.
Still, truly foul smells from discharge should always be treated as a red flag—hello, discharge that smells like onions.
It may not always be a cause for worry, but it could be a sign of a tampon left in for too long.
Discharge smells like metal but no period
Even with no period in sight, a metallic odor from your discharge is possible.
It still comes down to the presence of blood.
Slight vaginal bleeding can happen throughout your menstrual cycle for a multitude of reasons:
After sexual intercourse
Friction or slight irritation during sex can sometimes lead to light vaginal bleeding—especially if you’re contending with vaginal dryness.
It’s typically nothing to worry about, and it’s self-resolving, but it could be the reason for that slight period smell (even if it’s still weeks away).
Semen can also temporarily alter the pH balance of your vagina, leading to a slight metallic smell.
Minor vaginal injuries
And we mean minor: this could be minor vaginal tears from exercise or, again, having sexual intercourse.
These injuries can cause a minute amount of bleeding, which might not always be visible but could introduce a metallic odor to your discharge.
This type of vaginal bleeding happens when a fertilized egg attaches itself to the lining of the uterus—a critical step in early pregnancy.
Implantation bleeding is generally lighter and shorter-lived than a regular period, but it may be behind that copper smell.
Your discharge on birth control can go through a number of changes, from consistency to quantity.
But a distinctive metallic vaginal smell could be down to the light spotting that comes with hormonal contraceptions like IUDS (intrauterine device) or the pill.
And the root cause can vary.
While a metal smell from discharge is not a tell-tale symptom of hormone imbalance, it’s a very possible by-product.
If you notice your vagina smells like metal, but you aren’t on or near your period, it’s a good idea to monitor other symptoms you may be experiencing.
Especially if the smell comes with any symptoms such as:
- Vaginal itching or burning
- Pain when peeing
- Yellow or green discharge
- Pain during sex
- Bleeding after sex
- Pain in the tummy or pelvis
Is metallic-smelling discharge a sign of pregnancy?
When navigating the exciting (read: nerve-wracking) path to potential motherhood, it’s normal to scrutinize every change in your body for signs of pregnancy.
You know that during early pregnancy, your body undergoes a whirlwind of hormonal changes.
And these hormonal shifts can influence the vaginal microbiome.
So, could metallic-smelling discharge be a sign of pregnancy?
As we mentioned earlier, implantation bleeding could introduce a metallic scent to your discharge due to the presence of blood that contains iron.
Still, it’s important to note that not everyone will experience implantation bleeding, and the presence of a metallic smell is not a surefire sign of pregnancy.
Plus, there’s far too many other variables to be ruled out: hormone fluctuations, vaginal tearing, and bleeding after sex.
If you do suspect you might be pregnant, look out for other early signs of pregnancy, such as missed periods, tender breasts, and nausea.
But a pregnancy test will always offer the most certainty.
What does early pregnancy discharge smell like?
Typically, early pregnancy discharge is mild-smelling and looks clear or milky white with a thin consistency.
It’s often called leukorrhea even though it can be present outside of pregnancy too.
This is basically a sign that your vaginal health is solid and pH levels are good.
Of course, every person’s baseline of leukorrhea is different, so if yours is more pale yellow that’s OK.
Even a tangy smell can indicate you’ve plenty of healthy vaginal flora.
This is basically a stopper of sorts for your cervix, keeping baby protected from bacteria and viruses.
Later in pregnancy, you may even experience jelly-like discharge as your mucus plug sheds.
How to get rid of vaginal odor
Kind of over that your vagina smells metallic?
Hey, it’s OK to want to manage your vaginal odor.
As long you know that it’s largely natural, temporary, and absolutely nothing to feel shamed by.
But making your vaginal smell good begins and ends with maintaining a healthy vaginal pH balance.
That means avoiding scented soaps, gels, wipes, and vaginal douching—these will only disrupt the natural pH of your vagina.
Some healthy ways to keep your vaginal environment clean include:
- Showering regularly and drying yourself properly afterward
- Wearing breathable cotton underwear
- Changing out of wet clothing promptly
- Staying hydrated to help reduce odor-causing bacteria
- Using condoms to protect your vaginal flora.) during sex (and reduce the risk of STIs)
- Introducing probiotics into your diet to promote a stable vaginal microenviroment
And remember, everyone has their own unique scent, and it’s entirely natural.
The aim should be to maintain a healthy vaginal environment rather than eliminating the odor completely.
As always, the real flex is staying informed and knowing what normal looks like for your discharge.
A metal smell from your discharge, especially around your period, is common and often a sure sign your vagina is in full cleaning mode.
But it’s always worth opening the conversation with your doctor if you’ve any concerns or questions about changes in your vaginal health.
Especially if it comes with discomfort, pain, or persistent symptoms outside your norm.
Consider it peak self-care (for down there).
