I had the same thing happen to me about 2 weeks ago.

I tried a little plunger, found out it was the wrong one. My
brother went with me to pick out a good one. It worked!
But incase, you want to try another trick is to use vinegar
and baking soda, pour a generous amount of vinegar and
some baking soda. Leave it in for about 15-20 minutes and
it should clean out all clogged drains.

Don't worry this happens to all of us,at one time or another.
Why don't you use a wastebasket in the bathroom? That
way, your toilet won't clog.
Good luck and take care.
