Jude Sorry that you have not had any responses so far.
My experience is a bit diff from yours.
I had quadranectomy (Generous WLE) and a 2nd WLE for better margins. This left me with asymmetry between the 2 breasts.
I had reduction and uplift to good side and a complete reshaping of affected side in Jan this yr.
My 'good' side is very soft an sits v. slightly lower now than the affected side which is affected by fat necrosis. But overall is massively better than before.
I think the lowering of the 'good' side has been gradual and certainly 10 wks on from op all has settled. I think that it was about 6 wks when this had been achieved
So perhaps 2 wks a bit soon but can really understand your anxiety about this
