Please help, TMI!

So im at work and just used the bathroom. I felt a weird sensation, like it felt like a glob came out of my urethra. Sure enough when I looked in the bowl, there was a clear-ish white glob. It didnt hurt, just felt weird. Ive never had something like this happen before, so of course my dumbass went and googled it and now im scared shitless because im self- diagnosing 😑 From what I read, it could be a uti, kidney stones or a sti. It doesnt burn or itch, its not painful nor do I have a constant urge to pee.

Could it just be the normal mucus that comes out that flushes your system? if I could feel it to that extent I dont feel like its normal. Im freaking out and plan on making a appointment with Planned Parenthood. Any advice before I make the appointment??
