The closest thing to that would be to come out to a few trusted friends and ask that they refer to you with feminine pronouns or a new name, and see if you like it or not. You could explain that you want to try out these pronouns or name for a little while and see if they make sense for you.
If you don’t feel trans because you are worried that you are not feminine enough, remember that women can sometimes be masculine, and that you do not have to force yourself to fit into traditional gender roles, even as a trans person.
