Covid Isolation

hi all, new to this forum and just looking for some advice. i tested positive for Covid on 13/2/2021, symptoms started on 12/2 so i will be isolating until and including 22/2. My wife has just received her positive test result also (she took test yesterday 16/2) she has to isolate until 26th now. Do i also
need to extend my isolation period to 26/2 or do i stick with my original period?

any help appreciated.
