For the past 2 months I've been wearing a pad everyday because for some reason, there's been a weird wet spot (along the back of my vag area and the bottom of my butt) it looks kind of like a pee spot, but it isn't. it doesn't smell and I think it could be sweat, but I have no idea how to stop it, pads seem to work but its starting to cost too much to wear one everyday. any idea what it is or how to stop it?
