Idk what wrong with me?Help?Im like swallowing some bittter/salty tastein stuff when i snort?

You know when u get a cold and sometimes you sniff or snort and swallow your snot i guess?..lol. well for the past 3-4 days everytime i do it tastes terrrible!!! like it tastes salty/bitter like litterally disgusting though when i blow my nose its clear maybe some is alittle green. About 2 weeks ago i started getting sick it started with a stuffy and runny nose then 4 days later i started getting a cough. i no longer have a runny nose but i have a cough here and there. Im also 25 weeks pregnant so i dont now if that would have anything to do with what im all of a sudden tasteing...anyone know what this is?
