Minnie. So far the advice you have been given is sound. NO water until you have leaves!
The one you cut - it should ideally have been left to dry and callous before potting it up. Once you have that great callous (see picture) roots will come almost automatically but a fresh cut can allow pathogens in and you might have more rot. The fact that you had good white sap is a sign that you had healthy wood.
