Noticing that something feels different ‘down there’ for the first time can be confusing – and a little worrying too. Itching, soreness or changes in discharge are common signs, and if you’re not sure what’s going on, you’re definitely not alone.
Thrush is a condition that lots of women experience at some point, even during their teens. It can feel awkward to talk about, but there’s absolutely no reason to feel embarrassed.
Let’s break down what thrush is, why it can happen and what steps you can take next.
So…what actually is thrush?
Thrush is a common condition that affects the vagina and the surrounding area (the vulva). It’s caused by a type of yeast called Candida. This yeast naturally lives in the vagina and usually doesn’t cause problems. In fact, many women have it without even realising.
Thrush happens when Candida grows more than usual. This can lead to symptoms like itching, irritation or changes in discharge.
Healthcare professionals often describe it as a vaginal yeast infection. It develops when the natural balance in the vagina shifts, which can happen for lots of reasons.
It’s important to remember that thrush is very common. It isn’t caused by poor hygiene, it doesn’t mean you’re unclean and it doesn’t mean you’ve done something wrong.
Why thrush can happen for the first time in your teens
Experiencing thrush for the first time can feel confusing, but it can be linked to natural changes in hormone levels. Thrush isn’t usually seen before puberty, but it can occur during adolescence.
Can hormonal changes cause thrush?
During puberty and throughout your teens, hormone levels naturally change. These shifts can sometimes affect the natural balance of microorganisms in the vagina, which may make thrush more likely at times.
Can your period trigger thrush symptoms?
Hormonal changes during your menstrual cycle may also play a role. Some people notice thrush symptoms appear or feel worse a week before their period.
Can antibiotics cause thrush?
If you’ve recently taken antibiotics, they may sometimes increase your risk of thrush. This is because antibiotics may affect the balance of bacteria in the vagina, which may allow yeast to grow more easily.
Everyday day things that may trigger thrush symptoms
The skin around the vulva is sensitive. Things like scented soaps, shower gels, wipes or tight, non-breathable clothing sometimes irritates the area and may make thrush more likely.
Vaginal sprays or feminine washing products may also disrupt the balance of healthy bacteria. It’s best to avoid douching (washing inside the vagina), as this may affect that balance too.
Sometimes, there’s no clear reason
For many people, thrush happens without an obvious cause. Sometimes it just happens, even if you’ve done nothing differently.
Signs that something might not feel right
If something feels different or uncomfortable, it can be tricky to know what’s normal, particularly the first time you notice symptoms like these.
Some common signs of thrush include:
- Itching or irritation around the vagina and vulva
- Soreness or a stinging feeling when you pee or if you have sex
- A white vaginal discharge that may look a bit like cottage cheese and usually doesn’t have a strong smell
It’s also worth knowing that other conditions may cause similar symptoms, so it’s not always easy to tell what’s going on just from how it feels. That’s why it’s important to speak to a healthcare professional instead of trying to diagnose thrush yourself.
First time with these symptoms? Talk to a GP
If this is the first time you’re experiencing thrush symptoms, see your GP.
That might feel like a big step, especially if you’re feeling unsure or a bit awkward, but it’s actually a really positive one. Healthcare professionals are used to discussing intimate health, and their goal is to help you feel comfortable and supported. You can also ask for a chaperone or take someone you trust along to your appointment for extra reassurance.
Getting advice early means you can be sure what’s causing your symptoms. Conditions like thrush can feel similar to other things, so checking in helps you get the right advice for your situation.
If thrush is confirmed, you’ll usually need antifungal medicine to get rid of the infection. Antifungal medicines are available from pharmacies, including brands such as Canesten, but it’s important to check the most suitable option for you first with a healthcare professional.
Is thrush linked to sex?
Thrush isn’t a sexually transmitted infection (STI). It can happen whether you’re sexually active or not.
That said, some people notice symptoms after sex. It’s also possible, though less common, for thrush to pass between partners during sex.
If you’re unsure what’s causing your symptoms, it’s always a good idea to speak to a healthcare professional.
Simple everyday habits that can help
There are a few small things you can do day to day that may help you feel more comfortable and support your intimate wellbeing:
- Use water or a gentle, unfragranced product (like an emollient) instead of soap when washing the vaginal area
- Gently pat the area dry after washing rather than rubbin
- Wear breathable underwear, such as cotton
- Do not wear tight underwear or use scented soaps, wet wipes, feminine washing products, bubble baths and essential oils around your intimate area
- Avoid ‘douching’ (washing out the vagina with water or other products), as this can disrupt the natural balance of bacteria and yeast
These are simple, everyday habits, not strict rules. Everyone’s body is different, so it’s about finding what feels right and comfortable for you.
Feeling awkward talking about it? That’s normal
If you’re feeling a bit unsure about talking about thrush symptoms, that’s completely normal. Many people feel the same way, particularly the first time it happens.
Even though it might feel awkward, you’re not alone. Thrush is very common, and healthcare professionals discuss it every day. Their job is to help you feel reassured and at ease.
It can also help to talk to someone you trust, like a parent or another adult. It’s important to speak to your GP – you can ask to see a male or female GP if you have a preference.
You don’t have to figure everything out on your own. There’s always someone who can help you feel more confident about what to do next.
What to do if thrush comes back?
Thrush can sometimes come back. If symptoms keep returning or don’t improve, make sure to check in with a GP. They can help you figure out what’s causing your symptoms and ensure you’re getting the right advice.
It’s always best to check with a healthcare professional rather than trying to diagnose the problem yourself. This is especially true if your symptoms return or feel different.
Other places teens and young people can get trusted advice
If you’re feeling confused about your symptoms, there are trusted people and places that can help.
You might find it helpful to start by talking to a parent, guardian or another adult you feel comfortable with, who can support you and help you decide what to do next.
You can also speak to:
- A pharmacist (you can ask to speak in private)
- A sexual health clinic
You can also find reliable information on NHS websites.
You don’t have to manage thrush by yourself – support is there when you need it.
Experiencing thrush for the first time can feel confusing or a bit worrying, but it’s very common, and you’re not the only one going through it. Understanding what’s going on in your body and knowing where to turn to for advice can help you feel more in control. If you’re ever unsure about your symptoms, ask your GP for advice.
