Ok, phew. Scared me.
The dry food obviously won't help, and it may affect things for a few cycles.
Technically per guidelines you'd hold the dose for at least a week. The skipped shot does mess things up a little bit, but you had enough data before it happened (even if it may have been inaccurately low). Even if the Libre readings were good, you still have room for a 0.25U increase.
Can you do me a favor and insert a row (merge columns) above the the 22nd and say something like "Data for 4/22 and 4/23 believed to be inaccurately low and Libre malfunction". That way it's just more obvious to anyone reading, in case they happen to miss it or misunderstand the remarks column.
