Confused!!

[dontsitdown]

My son is self isolating since Friday but not showing any symptoms now except still being more tired than normal.
Do we all need to self isolate for 14 days or stick to the original 7?

We're in the same position here, self isolating since friday after developing normal cold symptoms, with a persistent cough. No idea whether I just carry on self isolating until Friday or whether I now need to have DH and DC isolate with me until the following Friday. Following to see if you get any helpful advice as I'm a bit confused and just want to do the right thing.
