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.

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.

Absolutely love the Period G String, it’s the underwear that got me into g strings. I prefer it over any other underwear with gym clothes regardless of whether I’m on my period or not. It is genuinely comfortable and prevents camel toe.
I have tried other period Gee’s that do not give me the confidence these do! They are also great for the gym as they are seamless so you can continue wearing tights and nothing shows.
I love them so much! They are so comfy and they don’t look tacky and still make me feel confident even when it’s that time of the month. They are for lighter days and I’m definitely wanting to buy the heavier period undies 💚💚💚 thank you!!
These are a life saver!! As someone who has always struggled with reactions from pads, and inconsistent flow for tampons, these are a game changer!!
I wear them everyday. Even when I am not on my period. As I work a very manual job. I get sweaty down there. These genuinely help with that too! I love them so much, I am now ordering different styles. Super comfortable, extremely absorbent, easy clean. They take about 1.5-2 days to fully air dry. But even still. I could not live without these!!
Wow. As a girl with a very heavy endometriosis flow, I am constantly bleeding through tampons, pads, thongs, etc. This has genuinely changed my life. I can wear a smaller tampon which doesn’t hurt as much AND still be protected from my flow AND workout in my sexy leggings with these thong panties. Iconic!!
Love this underwear. So comfortable and I haven’t bought panty liners in years. They G-string underwear doesn’t even feel like they’re period underwear. Love them they’re great.
