FemmyCup

I have a FemmyCup--low cervix and sometimes I can get it positioned correctly where it doesn't leak, others I don't think it opens completely. It's very thick & causes pressure that makes it hard for me to void my bladder. I have a very short Vagina (I can easily find my cervix with my very small hands/short fingers). Any recommendations for another brand? I've tried Insteads but my fingers are not long enough to get it placed correctly so it doesn't slip back out the minute I stand up.
