Hi all! I've recently made the decision to jump in and try a cup. However, I'm really not sure which one to try, so I'd love to buy one 2nd-hand if anyone is selling. I'm not sure about length but I know I have a small vagina, I have to use lite tampons or I get cramps. I also don't have a very heavy flow. Please let me know if you can help me out. :) Thanks!
