Sinus infection

I’m pretty sure I have a sinus infection. My throat was kind of sore yesterday but I woke up this morning and it’s uncomfortable, probably from the drainage. My nose isn’t stopped up, but it’s stuffy. So far I don’t have any colored mucus (sorry I know tmi) and I don’t have any sinus headaches.. so basically just the drainage and sore throat.

Should I go to the dr or just gargle some salt water and breathe hot vapors in to loosen up anything that may be in my chest/nasal cavities?

I’m 18 weeks pregnant if that makes any difference
