Replacement for the Diva Cup

I bought the small diva cup a few years ago because I didn't know there were any other brands. It is too long for me. I inserted it last month inside out and this was perfect. My flow is pretty heavy the first few days of my period and I tend to leak some with this cup. I would like to try something that might not leak as much. I would love any suggestions as I get overwhelmed with all that is out there.

Also, I don't have kids, but would like to someday soon. Would you recommend waiting til after childbirth to get something different or will I be able to use the same one? Thanks!
