First time Diva Cup. Thoughts? Mine, gross

Celeste
Ok day one of diva cup. I washed it many times, and had it in for maybe four hours now, and it already smells pretty bad. I was leaking a more clear blood after peeing, because my other Period blood is super dark and gooey. Good thing I wasn't in a public restroom for the first time because I had to put a leg up and pretty much push the thing out like I was giving birth. I washed it again and it still smells. Half of it was filled with blood.  Like am I just nasty or is this normal.
