I've used tampons since around 12/13 years old due to having a heavy flow and not liking pads. I'm now 27 and have been getting more and more annoyed at how much sanitary products cost me every month. So I bought this disc - I was wary as I've tried a moon cup before and really struggled with it, but this disc is honestly FANTASTIC.
Even on day 1 period, I am able to go about my day normally - I sometimes even forget I'm on my period, which is just amazing. I was really worried about leaking but I've not had any problems (the only time I have, is when I was still getting used to how to insert it properly). Also, you can absolutely have mess-free sex with it in.
There's definitely a knack to inserting it properly, but once you've got that, it's great! Periods just feel soooooo much easier.
