Give your GP a call, that's what we did in the end as nhs direct aren't a lot of help tbh.
I was really not sure about her having it or not.. but ended up calling the GP and DD (6) is now on Tamiflu. They are not swabbing any more just going on symptoms.
soon as we knew she was on tamiflu we then called the school, let various people know who we were due to have meetings with etc etc so they could cancel.
hope it' just a bug for your dd..
and thanks for the get better soon for mine :0
