If it is infinitely spatially extended, it either repeats simply, or it "never repeats"- but you can always find a repetition for any finite region. Since our awareness is finite, this means yes - it "repeats".

But we don't know if it is infinitely spatially extensive. We can only see a tiny part of it, as far as we can surmise. It "looks like it keeps going", outside the 50 billion light year sphere we're looking at right now.
