Yes
I rarely bother checking my brews for the first 3 day or so. The yeast doesn't know you're anxiously watching like a newbie parent willing their child to take its first steps, it'll do its thing in its own sweet time and it if really feels like yanking your chain, you'll get no foam, no airlock bubbles, no nothing, just a magically fermented beer. If you're really worried after 48 hours, take a hydro sample. If it the same as the original gravity when you pitched, you may have a problem that needs to be solved.
Until then, relax
