Would “trying out” hrt be a bad idea?

Over the last year or two I’ve (AMAB) had the occasional period where I’ll seriously question my gender for a few days, and then be perfectly comfortable being a cis man. I’m having a really hard time knowing or accepting that I may actually be trans.

I have spent a lot of time during these periods of questioning and wondering what it would be like on E. What I’ve heard about the mental changes in particular have made me curious (maybe just in a cis “I wonder what it would be like to be a girl” type of way?). Would it be possible for me to maybe try hrt for a short period, like a week or two (before permanent effects happen), just to see if it would confirm to myself if I’m trans or not? Is this a bad idea?

Edit: I appreciate everyone’s comments. They’ve given me a lot to think about.
