Yup adjust your chain, and check your tension along the chain's length to see how many tight and loose sections you have. I just replaced my chain and sprockets for this exact reason, although at 26000km, (original chain) mine was WAY worse, but the exact description OP listed. Get ready to change your chain and sprockets together.
I ride to get lost and find my way back.
