Pregnancy rhinitis ? Anyone else deal with it before

Eren

I pretty much self diagnose but for 3 weeks now I am so congested I can’t breathe at all unless I use a oxymetazoline spray. I tried regular saline spray but it’s not helping at all, after a few minutes of severe congestion I feel like I’m drowning and I can’t help but use my spray. I am now also getting sinus headaches. What should I do !!?? I feel miserable
