Valid Confession?

[Maximilianus]

I realize that this is my scrupulosity acting up but this has been nagging me.

I failed to do the sign of the cross at the begenning of the rite.
Usually the priest says the prayers including the sign of the cross but this one didn't, or maybe I missed it. I didn't think much of it until I finished the confession.
My confession is still valid right?

As long as you had true contrition for your sins confessed them and received absolution your sins are forgiven
