If thrush seems to follow your cycle around, there may be a reason. Australia's government-funded health service healthdirect says vaginal thrush is most common in people who have regular periods, and lists higher oestrogen levels among its triggers.
That makes "yeast infection and periods" one of the most practical topics in vaginal health. Below: what Australian health sources say about timing, period products and treatment.
Quick answer: A yeast infection can occur during or around your period; Australian guidance links thrush to menstrual cycle changes and higher oestrogen levels. Choose unperfumed pads or tampons, keep the area dry and complete the full antifungal course. If thrush returns 4 or more times a year, see your GP about longer treatment.
Why do I get thrush around my period?
Hormonal shifts are the likeliest link the sources point to. The Better Health Channel lists menstrual cycle changes as a trigger, together with recent antibiotics, the oral contraceptive pill, pregnancy, diabetes and iron deficiency. healthdirect names higher oestrogen levels and menopausal hormone therapy. Neither site pins down an exact day of the cycle, so tracking your own pattern is the most reliable guide.
Can you have thrush while on your period?
Yes, the two can overlap. Thrush is an overgrowth of the yeast Candida albicans, and having a period doesn't stop that process. Typical signs include itching or burning around the vulva, thick white or creamy discharge that may look like cottage cheese, pain with sex or urination, and redness or swelling.
Which period products are best when you have thrush?
Unperfumed ones. Better Health advises avoiding perfumed toilet paper and perfumed menstrual products, as well as tight pants and synthetic underwear. healthdirect suggests loose clothing and cotton underwear, and avoiding soaps, bath oils, vaginal hygiene products and lubricants during treatment.
If you use a period cup (a menstrual cup) or tampons and you're treating thrush with a vaginal cream or pessary, check the product leaflet or ask your pharmacist about timing before inserting anything during the course.
How is thrush treated if my period arrives mid-course?
Talk to your pharmacist about how to fit the course around your bleed. Australian pharmacies stock antifungal creams and pessaries, usually used for one to seven days, and a single fluconazole tablet; healthdirect stresses finishing the full course. Fluconazole isn't recommended in pregnancy, and thrush creams can weaken condoms, so Better Health suggests applying them after sex.
When to see a GP
- it's the first time you've had thrush symptoms
- pharmacy treatment isn't working
- you're pregnant or breastfeeding
- you have lower abdominal or vulval pain, sores or abnormal vaginal bleeding
- you're worried you might have a sexually transmissible infection
- you've had 4 or more episodes in a year (recurrent thrush, which usually needs about 6 months of treatment)
A fishy smell is more typical of bacterial vaginosis. Our guide to bacterial vaginosis covers how it differs from thrush.
Frequently asked questions
Is it normal to get thrush every month before my period?
Australian sources describe menstrual cycle changes as a trigger, so some people do notice a monthly pattern. Repeated episodes still deserve a check-up: Better Health recommends seeing your GP if you have 4 or more episodes in a year, as recurrent thrush usually needs around 6 months of treatment.
Does the pill make thrush more likely?
Better Health lists the oral contraceptive pill as one of several thrush triggers, and healthdirect mentions higher oestrogen levels. That doesn't mean you should stop your contraception. If you think your pill is linked to repeat thrush, talk to your GP about whether another option might suit you.
Can I self-treat thrush during my period?
healthdirect says self-treatment is generally safe if you've had thrush before, treated it successfully and are sure of the symptoms. Ask your pharmacist how to time a cream or pessary around bleeding. If it's your first episode, or you're pregnant or breastfeeding, see your doctor first.
How do I clean my period cup after thrush?
Use your usual routine from our cleaning page. Lunette's care advice is: Boil 5 minutes before first use and after each completed cycle. For questions about reusing products after an infection, your pharmacist or GP can give advice based on your history.
For the cycles ahead, the Lunette period cup is made of 100% medical-grade silicone and lasts up to 10 years with proper care. Our cleaning guide walks you through it.
