Annoying clogged ear at 19 weeks

Nadine

^^^ this is how I feel about clogged ears!

So I noticed around 15 weeks whenever I would sleep on my left side my ear would completely clog. When I would wake up and sit up it would go away.

This weekend I went to Florida and did some swimming(BIG mistake apparently)and now I can’t hear anything out of my left ear and it doesn’t seem to be going away.

I read that it could be a pregnancy symptom due to retaining more water and that it goes away after giving birth, but idk how I’m going to deal with this for another 20 weeks.

Any suggestions for getting rid of this terrible annoying feeling?
