Adjustment of Status - I-485

I have a very confusing question , I got done with my interview based on marriage that took place in Cleveland on 01/12/2017
the morale of the story that's the interview went really smooth and IO was really nice and positive since we already have a baby together and other one is on the way and our marriage is legit , he was just teasing us at the beginning but by the end of the interview He gave as a paper got check on a box say's "Your application/petition is Recommended for approval" but the weird the thing the officer didn't ask for i-94 or passport, when should i hear from uscis because my case did not update yet is there is anything wrong, because people say after the interview they most likely if the IO said everything looks good it will be updated few hours later or days, I know I'm still on my second business day, I'm just curious.
