CAN SOMEONE PLEASE GIVE ME SOME PERIOD ADVICE!!!!!?

So I've had my period for a little over a year and I'm going on vacation in a couple of days and I'm going to have my period. I want to try to use tampons (I've never used one before). I wanted to know if it would be okay to try to put in a tampon now (when I'm not on my period) so that I kind of know what Im doing on vacation. Is it going to hurt since it will be dry? Should I just wait? PLEASE HELP IM ALSO REALLY SCARED!!!!!!!!!!
