Natural cold remedies?

Send help I’ve been fighting off a cold/sinus issue for two months now. I’m 24 weeks pregnant and I swear every time I’m pregnant (this is my 4th) I get a cold , but this one isn’t going away. My nose is stuffy/runny, I have a headache, my ears feel clogged like I’m underwater no matter how much I pop them, and I have an occasional cough but it’s not bad.

I’ve taken the medicine (Im usually against medicine but I was desperate) my OB suggested and it didn’t help, I asked her what else I could do and she told me to ask my primary care doctor... who in turn told me to ask her.

I’ve gone outside just about every day to get natural light and fresh air, drank (sugar free) orange juice almost every morning, I have been eating healthy, etc.

What else can I do? 🤦🏻‍♀️
