Almost Fainted While Trying To Insert?

Lauren

So I decided to try a Diva Cup and got one. Boiled it. Read all the instructions. Relaxed in the shower and got ready to stick it in. I used the punch down fold and while I was able to find the hole when I got probably a quarter of it in (lots of pressure that was uncomfortable but not painful) I started getting dizzy. I stumbled out of the shower and laid on the floor until I didnt feel like I was about to faint again. Has the happened to anyone else? Am I doing something wrong? I'd like to try again, but I really wouldn't like to end up butt naked and unconcious on the bathroom floor. 21 no kids if that helps.
