Shower Drain Clogged?

So our shower drain reached the pinnacle of clogged this weekend. It's been slow for a long time and we've tried Liquid Plummer, poking around with a wire hanger and even getting a plumbing snake to send way down through the pipe. Nothing much really came up though. This morning after one shower, it was done for. 2 hours later, I still couldn't take my turn because it just wasn't draining at all. I had decided to call a plumber, but in one last move of desperation (I wanted a shower NOW!) I took the toilet plunger to it. A couple of good plunges did the trick! Whatever the clog, it freed up and everything drained in a few seconds. I don't know if this is plumber recommended or if there is any risk to your plumbing but for now, I get to shower. I will check in with a friend of mine who is a plumber and see if that was an OK thing to do. I'll keep you posted...
