Worried like crazy

I'm 14 weeks tomorrow , from My last period day . I went to bed Sunday just fine and woke up on Monday with the soar throat , went to work , felt worse my nose is clogged , my head hurts and sometimes my muscles feel soar too . I stayed home today , I didn't take medicines , just lots of herbal teas with vitamin C and healing qualities . I don't have fever though. I read that I should be in bed constantly but I have couple important meetings tomorrow and because I skipped today I would rather go it tomorrow .
