Blocked nose

I got sinus plus preg 18weeks my nose keep getting blocked and runny like once a week unfortunately I work in office and every two weeks my boss will chase me home to see a doctor. Evrytime the doctor requests for swab which irritates my nose further sooo badly blocked now I can’t sleep can someone teach me how to break this vicious cycle 😭I just swabbed again today and honey lemon is not helping. Too afraid to see doctor later they wanna swab me again I don’t want to be swabbed everyday doesn’t help my nose it’s soooo irritated
