peeing by accident!

Hey guys so this is an embarrassing problem. I've noticed sometimes that I pee by accident. Nothing crazy just a few drops in my panties but it's enough to annoy me and make me worry about it all the time. I thought this only happened to older people is something wrong with me? Like no matter how much I try I cannot stop from doing this! And it happens regardless if I have to go or not, and no this is not a UTI, I've had those before andante I just have a muscle problem?
