Have Questions?
AuntFlo Will Answer...
What if I get the wrong size?
Uh oh, you've grabbed the wrong size...
Unfortunately, due to AuntFlo products being labelled as Sanitary products, we are not able to switch these over for you. You will need to keep these.
Returned sanitary products cannot be resold, despite claims of them being unused, unworn, and unwashed. This is to maintain and uphold strict hygiene, health, and safety standards to protect our customers and warehouse staff.After all, we’re not only here for the planet, but also for your health!
However, if you are a first time customer with us, we can gift you one pair of underwear (in your correct size) if you have accidentally initially purchased the wrong size.
Please email us at hi@auntflo.au to chat more about this!
Do I wear them on their own?
Depending on your flow, and the absorbency level of the underwear you have chosen, you can wear our period undies on their own, or with some added protection.
Take some time to figure out what works best for you! Every period is a unique one.
Is AuntFlo free from PFAs?
Our period undies are also PFA free. PFAs are absolutely not part of our AuntFlo product design.
How often should I change them?
Knowing when to change your period underwear depends on a few factors, such as your flow, the absorbency of the underwear, and your personal comfort. Here are some general guidelines to help you determine when it’s time to change:
1. Flow Level
- Light Flow: If you have a lighter flow, you may be able to wear your period underwear for up to 8 hours without needing to change, depending on the product's absorbency rating.
- Moderate Flow: For moderate flow, you should change your period underwear approximately every 6-8 hours, especially if you feel any dampness or discomfort.
- Heavy Flow: On heavy flow days, it's best to change your period underwear every 4-6 hours to prevent leaks. You may need to change more frequently depending on the volume of blood absorbed.
2. Signs of Full Absorbency
- Feeling Damp or Wet: If you begin to feel moisture or dampness through your period underwear, it’s a sign that it has reached its absorbency capacity, and you should change them.
- Discomfort: If the underwear starts feeling uncomfortable or you're aware of the fabric sticking to your skin, it's a good idea to change them to maintain comfort and hygiene.
3. Personal Comfort
- If you start feeling less confident or comfortable, even if the underwear hasn't reached its absorbency limit, it's a good idea to change them. Comfort is key to feeling confident and secure during your period.
4. Activity Level
- If you're very active, especially if you're exercising, swimming, or moving around a lot, you might need to change your period underwear more frequently. The increased movement can cause absorption levels to change, and you may feel more comfortable changing to ensure there are no leaks.
5. End of Day / Overnight Use
- If you’re using your period underwear overnight, you may want to change them after 8-12 hours, depending on your flow. Consider pairing them with a menstrual cup or tampon for additional protection if you experience a very heavy flow.
Overall, always listen to your body and make changes when you start feeling uncomfortable, to maintain confidence and hygiene.
