Why do I smell after my period?

A little smell is normal

First things first — a subtle change in scent right after your period is completely normal. Menstrual blood is technically old blood, and it has a slightly metallic or musky smell. For a day or two after your period ends, you might notice this lingering.

This kind of mild, temporary shift isn't something to worry about. It usually resolves on its own within 24–48 hours with normal hygiene.

When it becomes not-normal

The kind of after-period smell that's worth paying attention to is different:

• Strong, fishy odor that lasts more than 2–3 days after your period ends
• Odor you can smell through underwear or that others might notice
• Odor paired with thin, greyish discharge or a change in your usual discharge
• Odor accompanied by itching, burning, or discomfort

What's actually happening down there

To understand why period-time is a vulnerable window, you need to know one thing: vaginal pH.

A healthy vagina has a pH between 3.8 and 4.5 — quite acidic. This acidity is the vagina's natural defence system. Good bacteria (lactobacilli) produce lactic acid, which keeps the environment hostile to the bacteria that cause odor and infection.

When you're on your period, menstrual blood has a pH of around 7.4 — almost neutral. This raises the overall vaginal pH temporarily, making it less acidic for a few days.

For most women, pH returns to normal within a day or two after their period ends. But if something else is going on — recent antibiotics, a new partner, tight synthetics, stress — the pH can stay elevated. That's when bacteria that don't belong start to overgrow, and that's when odor becomes a persistent thing.

Everyday things that make it worse

These are the most common contributors to persistent post-period odor:

• Scented pads and tampons. Fragranced menstrual products can disrupt the vaginal environment.
• Tight synthetic underwear during your period. Warm + moist + no airflow = bacterial party.
• Douching or "cleaning inside." Never do this. The vagina cleans itself. Douching wipes out the good bacteria and worsens odor.
• Waiting too long to change pads or tampons. Change every 4–6 hours during your period.
• Using scented body wash near or inside the vulva. Plain water is enough. Soap disrupts pH.
• Not showering after sex during your period. Semen has a pH of 7.2–8.0, adding to the alkaline load.

How to help balance return

The good news: for most women, restoring balance after a period is straightforward. Here's what actually helps:

• Switch to unscented pads or tampons — or better, a menstrual cup, which doesn't affect pH the way disposables can.
• Wear cotton underwear during and after your period. Change them daily.
• Rinse externally with warm water only — no soap inside, no wipes with fragrance.
• Support your vaginal pH — this is where products like Vagiclav come in. Used after your period ends, they help push pH back down to the healthy acidic range so the good bacteria can dominate again.
• Take a lactobacillus probiotic — helps repopulate the good bacteria your body relies on.

When to see a doctor

Occasional post-period odor is normal. See a doctor if:

• Strong odor persists for more than a week after your period ends
• You have pain, fever, or unusual bleeding alongside the odor
• The odor comes with green, yellow, or unusually thick discharge
• You're pregnant or trying to conceive
• This is the first time you've had a strong odor and something feels off

How Vagiclav fits in

After-period odor is one of the most common reasons women reach for Vagiclav. The routine is simple: use one insert at bedtime for a few nights after your period ends. This is exactly the window when your vaginal pH is trying to reset, and Vagiclav is designed to give it a nudge back to the healthy acidic range.

Many customers make Vagiclav a monthly post-period habit — 3 to 5 nights right after their cycle ends. Discreet, no daily maintenance, and works while you sleep.
