Liquid in ears / need to pop them?!?

Since I was at 9 weeks, I've had a hard time with my ears being "clogged" like they need to be popped. It is only when I'm vertical. I've tried Claritin, Tylenol, chiropractor...anything I can. Trying Sudafed next.  I can hear myself get super dizzy.  All the doctor said was try Sudafed now. Anyone else experience this and get rid of it?
