Sick and pregnant 😷🤒

So I'm 25 weeks, and I've had a scratchy throat the past couple of days and tried catching it early with safe OTC meds, warm tea, and a vitamin C supplement. But today I woke up barely able to talk, stuffy/runny nose, congested, coughing up phlegm and my chest feels heavy when I breath.

I tried calling my doctor, but I got voice-mail so I'm waiting to hear back, and I think their office is closed this whole week. Figured I'd ask you ladies to get some opinions.

Does this sound bad enough that I need to be seen immediately (like ER?) or should I just keep doing OTC and wait it out?
