fever???

Steph.
Tuesday I woke up with a bad sore throat. Wednesday I still had it so I went and got antibiotics. Last night (Thursday) I started to lose my voice. Today I have a much better but still sore throat, no voice and now a log grade temp. Baby is showing no sick signs so that is good. 
Is it normal to get a low grade temp 3 days into antibiotics?  Little man is still nursing as they said it's safe. Tonight my DH is taking care and giving pumped milk so I can rest.
