Keeping this anonymous because very personal but my discharge has no smell and for the most part white sometimes a grayish or slightly a light brown/yellow but is very thick but I do not itch at all and has no smell?? I also have an IUD and do not have periods at all, just thick discharge like this?? I just want to know why and if I’m okay? I don’t think I have an STD or any type of infection because I never smell or itch but why do I have discharge like this is it normal
