Vaginal discharge, also called cervical mucus, is a topic that intrigues (and sometimes worries) many women. We notice it in our daily lives, but we don’t always feel comfortable asking questions about it.
Is it normal to have it? Why does its appearance change? Could it be a sign of a problem?
In short, lots of small questions that deserve clear and reassuring answers.
In this article, I’ll explain what’s normal, what might indicate you should consult a doctor, and above all why knowing the different vaginal discharge types is actually a precious ally to better understand your body.
Is vaginal discharge normal?
Absolutely!
Vaginal discharge usually appears during adolescence, when the menstrual cycle becomes active, and it accompanies us all the way to menopause.
It’s simply a natural part of life for everyone who menstruates.
Having vaginal discharge is actually a sign that your vagina is healthy and that your cycle is working properly. It’s produced by the cervix and the vaginal walls, and its role is to protect, hydrate, and naturally cleanse the vagina.
However, in some cases it can also be a sign of an infection, an imbalance in the vaginal flora, or irritation.
Here are some guidelines to better understand it:
-
White or clear discharge: a sign that everything is fine! The texture varies throughout your cycle (creamy, watery, or stretchy).
-
Yellow or greenish discharge: if it’s thick and comes with a bad smell or itching, it may indicate an infection (yeast infection, STI, vaginitis, etc.).
-
Red or pinkish discharge: outside of your period, it can be linked to irritation, a small tear, or even ovulation spotting.
-
Grayish and foul-smelling discharge: often associated with bacterial vaginosis.
Most of the time, when there’s a problem, other signs appear as well: strong odor, unusual texture (clumpy, foamy…), itching, burning, or pain.
If you notice an unusual and persistent change, it’s best to consult your gynecologist.
What is the purpose of vaginal discharge?
First of all, discharge is directly linked to your hormonal cycle.
Estrogen and progesterone directly influence its amount and texture. That’s why it changes throughout the month.
Here’s what it looks like:
-
When your discharge is clear, watery, and stretchy like raw egg white, you are usually in your fertile window. This type of vaginal discharge nourishes sperm and helps them travel to the egg.
-
When it’s creamier, thicker, or sticky, it forms a sort of “barrier” that makes it harder for sperm to get through.
Result: vaginal discharge plays a key role in fertility. It can help you whether you want to conceive or avoid pregnancy (this is actually one of the markers used in the symptothermal method).
But that’s not all! Cervical mucus also helps protect your vagina: it naturally clears out dead cells and keeps your vaginal microbiome balanced. Basically, it works like your body’s “self-cleaning system.”
Recognizing Your Fertile Window Through Vaginal Discharge
As you can see, the consistency of your vaginal discharge is not random. It is directly influenced by your hormones, and therefore by your fertility.
By observing how it changes throughout your cycle, you can get a fairly accurate idea of when you are fertile and when you are not.
In most cases, we see a similar pattern, although each person may have slight variations.
Follicular Phase
This phase starts right after your period ends and continues until ovulation (around day 14 if your cycle lasts 28 days).
At the beginning, it’s common to have a few days with no vaginal discharge. Then, progressively, the body prepares for ovulation and starts producing cervical mucus.
The first vaginal discharge of the cycle is often creamy, thick, and white, a bit like yogurt. This signals that your body is preparing for ovulation and that your fertile window is beginning to open.

Ovulatory Phase
As you approach ovulation, your vaginal discharge changes: it becomes more transparent, slippery, and elastic, like raw egg white.
This is a sign that your estrogen levels are at their peak and your body is ready to release an egg.
On the day of ovulation, you might even notice a very watery discharge, almost like water. If you’ve ever felt a little “splash” and thought you had peed yourself, don’t worry: it’s just your body signaling that you are at your fertility peak.
At this point, cervical mucus is the most welcoming for sperm: it nourishes them, helps them survive, and guides them toward the egg. This is therefore the time when your chances of getting pregnant are highest.

Luteal Phase
Once ovulation is over, progesterone takes over and changes the cervical mucus.
Your vaginal discharge then becomes thicker, creamier, or even sticky. Sometimes it may almost disappear completely.
When you notice several days with little or no discharge, or a more compact texture, it’s often a good sign that ovulation has ended.

A Word of Caution
Even though your vaginal discharge provides lots of information about your fertility, I don’t recommend relying on it alone to know when you’re fertile.
For more accuracy, you can use symptothermal method, a technique that combines observing cervical mucus with taking your basal body temperature (and sometimes checking the cervix position).
It’s the natural contraception method I’ve been using for years, and I explain everything in detail in this article.
Vaginal Discharge with Hormonal Contraception
Hormonal contraception (pill, implant, vaginal ring, hormonal IUD, patch, etc.) affects cervical mucus because it directly acts on the hormones that regulate the cycle:
-
Fewer variations: under hormonal contraception, the natural fluctuations of estrogen and progesterone are blocked. As a result, cervical mucus is often more stable (less texture changes throughout the month).
-
More uniform appearance: some women notice their vaginal discharge is creamier or thicker, with fewer periods of clear, stretchy mucus (which normally signals ovulation).
-
Variable amount: depending on the type of contraception and individual sensitivity, some women have less discharge, others more.
-
Less fertile mucus: hormonal contraceptives are designed to make cervical mucus thicker and impermeable, preventing sperm from passing through.
Frequently Asked Questions
1. Are vaginal discharges normal?
Yes, completely normal! Vaginal discharge is naturally produced by your vagina to protect, hydrate, and keep it healthy.
It’s actually a great indicator that your body is functioning well.
2. Is it normal to have vaginal discharge every day?
It depends on each person.
Some women have a little every day, others only at certain times of their cycle (for example around ovulation). There’s no universal rule: what matters is knowing your own rhythm.
3. What’s the difference between normal vaginal discharge and a sign of infection?
Normal discharge is usually clear or whitish, sometimes a bit more abundant at certain phases of the cycle.
However, if it becomes very thick like curdled milk, turns yellowish or greenish, or comes with itching, burning, or bad odor, it’s often a sign of an infection (yeast infection, bacterial vaginosis, etc.).
4. Is a lack of discharge a sign of a health problem?
Not necessarily! Some women naturally produce less discharge than others.
But if you notice a sudden change (for example nothing when you used to have it), it could be related to your contraception, a drop in hormones, or menopause. In that case, it’s worth discussing with your gynecologist.
5. Why does my vaginal discharge sometimes have an odor?
A slight odor is normal: it means your vaginal microbiome is doing well.
But if the odor becomes strong, unpleasant, or unusual (for example fishy or very sour), it’s often a sign of imbalance or infection.
6. Can stress or diet change my vaginal discharge?
Yes! Stress affects your hormones and can therefore change the amount and appearance of your discharge. The same goes for diet: too much sugar or alcohol can disrupt your vaginal flora.
On the other hand, a balanced diet rich in probiotics (yogurt, sauerkraut, kefir, etc.) can help keep your vagina healthy.
7. When should I see a gynecologist about my vaginal discharge?
If you notice a sudden change, strange color, persistent bad odor, pain, burning, or itching, it’s time to consult a professional.
Basically: whenever it’s outside what’s normal for you, it’s better to ask for a professional’s advice.
As you’ve probably understood, vaginal discharge isn’t there by chance. Most of the time, it’s completely normal and even very helpful to better understand what’s happening with your cycle.
