Hi KevinTMC,
I would agree that it’s “normal” and it normally takes a few weeks for a new mattress to “break in” and to get used to a new type of mattress and sleeping surface than you have been used to (see post #3 here).
I would also agree that you did well
I hope you have the chance to share an update once you’ve been sleeping on your mattress for a few weeks.
