excel – If cell is updated, write cell value and timestamp in next blank row

I’m trying to update a column with timestamp and another column with updates (which got from a specific cell).

Desired behaviour:
A2 has xy written to it. That change triggers a macro, which puts timestamp in C column at row 2 and the update in D column row 2.
If new update is made in A2: If C2 is not empty, jump to C3 and put timestamp and put update on D3 and so on.

Unfortunately, it puts the first update timestamp and the update to the columns, but if I update again, it doesn’t jump and put update there.
