Nasal Congestion

Ever since I got pregnant, I feel like my nasal Congestion got worse. Before pregnancy, I also have rhinitis and sinusitis. I also have some allergies to animal fur and pollen. However, they were very manageable. But now that I'm pregnant, my nose is perpetually blocked, and also itchy and sneezy. Does anyone else also have a sudden increase in inflammation in the nose that is causing congestion? or maybe it's just a stand-alone problem for me, cos I already have pre-existing problems? ☹️☹️☹️ What can I do to relieve this? I want to avoid taking any medication or steroid nasal sprays.
