Good allergy remedies while pregnant?

I get seasonal allergies every single year around this time, I got tested for COVID already and I’m negative so it’s not corona. My entire face is full of mucus that will not come out. I’m using a nasal spray, taking robitussin for my cough and have been trying the steam method to sit with my face over a steaming cup of tea or water. I need a way to get rid of this quickly because my job doesn’t want anyone with “COVID symptoms” even if I show that I’m negative. I know I’m not the only one with bad seasonal allergies! What do you mamas do to cope?? I’m so uncomfortable and can’t sleep at all.
