Virus for 7 days...

Dawn • After 2 MMCs and 2 CPs in 2016, our 🌈👶🏼 is due 10.17.17.
So I'm 8 weeks 3 days and have been fighting a respiratory virus since last Monday. My symptoms were manageable, but they worsened yesterday. Today has been the worst so I'm worried this will turn into a sinus infection. Horrible congestion, drainage, and sinus pressure. There is really nothing medically I can do this early in my pregnancy. Any suggestions? I know rest is important, but I have severe pregnancy insomnia so that had not been going well for 5 weeks now. I've been drinking lots of fluids and using a humidifier. I really don't want to call out sick tomorrow as I'm trying to save all my time for maternity leave. Thanks in advance!
