I pitched a sachet of yeast, yes I added oxygen right after I pitched the yeast. I am fermenting at 62 degrees and the OG was 1.056
Sounds good so far. Did you rehydrate the dry(I'm guessing dry) yeast or just sprinkle on? What process did you use to add oxygen? Is your 62 degrees controlled or ambient?
Everything you have described so far sounds about normal really. Check the gravity in another couple days to see where you are.
