Sinus issues

Je
I will be 8 weeks tomorrow and I have a sore throat, sinus headache, congestion and even sometimes a runny nose. Does anyone know any safe remedies to relieve the pressure in my head. I can't afford to take off work right now since I just took off an entire week earlier in the month and have days off due to weddings coming up. I just need to make it through the day and not harm my baby.
