I’m fed up with period pants and disposable pads. I’m getting recurrent thrush, uti’s and general discomfort. While doctors are trying to help, I need to try re-usable pads. They all seem to have a PUL or recycled bottle layer for the waterproof element. I would like to try the most natural and less irritating products available, anyone any suggestions? I can only wear 100% cotton or bamboo knickers. My periods vary in heaviness - prefer less bulky and change more on heavier days. Thanks
