If her cough is productive and the fever isn't too high, then wait until you see your Homeopath.
If you think she is getting really bad, you could call the Homeopath and tell him/her what is happening now - so she has a note of it (and if she feels Bay needs something now - she will likely say so - and either prescribe something or say to bring her in).
Also, fever - as long as it isn't prolonged and too high, is acutally a good healthy response. Let it run its course - as long as it doesn't spike too high.
Hope she feels better soon
