help!!! new to mestrual cups!

Hey all!
I am looking to switch from tampons and pads to a mestrual cup, but I really am having a hard time figuring out which one is probably best for me! There seem to be so many kinds 
Any suggestions/advice much appreciated!! I am a 22 year old female, no kids, and I am kind of petite (I'm 5'5 and weigh about 114). I don't think my flow is especially light or heavy--pretty average.
Thank you so much😊
