Bought my first cup

I just got myself the Diva Cup (1) the other day. I actually just finished my cycle last week, so I haven't gotten a change to use it. I'm kind of excited & nervous about it. I've been using tampons since I got my period so trying to get it in doesn't concern me. I'm worried though I might not be able to get it in comfortably or what if I can't get it out. I've thought what if I can't reach well enough or grip. Idk. Just some thoughts on what I should expect or tips that might make my life easier trying to use it.
