Allergy eye drops?

Amanda
I've been using Benadryl for allergies, but it doesn't seem to take care of my itchy eyes so well. Does anyone know of a safe allergy eye drop? I don't know if eye drops matter too much when it comes to pregnancy, but I would rather be safe than sorry. I usually use Alaway, but it's listed as a category C drug. Any help is much appreciated! I can't stand how itchy my eyes have been.
