My bathroom sink has been draining very slowly for a couple weeks. Drano has not helped. The suddenly yesterday, my shower is doing the same thing and my toilet water was low. When the shower water went down the toilet water went back to normal. This morning once again the shower drained slowly and the toilet clogged.

Pretty typical of a clogged main drain line. You will most likely need someone to auger out the main line. Have them check the vents too.

Thank you! I should add that I have a septic tank... does that make the answer any different?

If the septic tank was full, it would probably not drain. However, when was it last pumped?
