Clogged/ringing ears?

My left ear has been clogged for MONTHS. It was muffled but is now ringing. It's not totally uncommon for me when I'm having sinus issues. But to go on this long is driving me crazy.

I've tried wax removal drops, regular peroxide, pseudoephedrine, Flonase, Zyrtec, and holding my nose/blowing. NOTHING WORKS. I asked my doctor Monday and she said it's probably just sinus related and since it doesn't hurt there's nothing she can do.

Has this happened to anyone else? I'm about to lose my mind. I'm 20 weeks.
