Spacetime itself was infinitely small, so not necessarily.
We don't know anything at all about the physics of infinitely small spacetimes, because we don't have a fundamental physics of spacetime at all.
GR is a descriptive approximation of the behaviour of spacetime, but says nothing about the fundamentals that generate that behaviour.
