The figures, for anyone assembling their own picture. If you are going to change something, change one thing and give it long enough to express itself. Four weeks is the usual minimum for anything pharmacological on this board, and two weeks of data has told you almost nothing.
Ask again with the specifics and you will get a better answer than this one.
A narrower follow-up, since the general answer is now clear:
What did you change at the same time, and can you separate the two now?

Careful with the causal language. Two things moving together in a period when five things changed is not a mechanism, and stating it as one makes the thread less useful to somebody reading it later.
Happy to go further on any of that.

That is right, and it stops being right at the edges. The general case is well behaved; the interesting cases in this thread are all at the boundary where the general case breaks.
Closing the loop on my own question.
Update, and it is the boring outcome: nothing was wrong. The measurement I was reading had moved less than its own week-to-week variation, which somebody said upthread and I did not believe.
