Allergy medication?

So I’m 9w1d and I’ve been very dizzy for a few weeks now.. my ob is sending me to get my ears checked since I have been really stuffed up/full ears and told me I could take a Claritin daily. I don’t know why it’s so different during pregnancy because I used to take it occasionally when not pregnant but seems to make me feel drugged and awful when I take it! But does clear me out and apparently could clear the fluid/mucus from my ears as well. So question is does anyone else have this issue and is Zyrtec maybe a better option? I read Zyrtec can make you more sleepy and pregnancy nausea/fatigue is pretty off the charts right now so don’t want to add to it! Which do you prefer? And yes I have tried a neti pot which does help but for some reason makes me more dizzy when I start using it ☹️
