Hey guys! I have a quick question. Does anyone else have any issues with the cup moving around while you're laying down and letting leaks get by? I use a DivaCup and apparently, you're supposed to be able to sleep naked with one, but if I did, there would be blood all over my bed because depending on the position I lay in, it decides not to work and catch blood. Is it because I am not putting it in correctly, or is this a problem some others of you face? Thanks!
