My nose is going crazy!

Who is dealing with congestion? I did not have this symptom with my first two! I have bad allergies and take my Zyrtec daily. I am fine outside in the warm weather but when I get home my nose closes up! How long will this last!? I have been dealing with this for almost 6 weeks. I am currently 10 weeks. I have done breath strips , humidifier, steam, Flonase, constant dusting, and pretty much everything else recommended! Is there light for me or is this going to continue for the next 200 days!?
