Adjustment of Status - I-485

So I had my AOS interview today, me and my legitimate US citizen wife were sworn in and everything went fine with the lady that interviewed us. She was nice with all questions asked and we all joke about stuffs. Though I done have enough joint stuffs with my wife but we both have joint bank accounts together, and my name is not on the house rent lease yet but my name is listed on it as an adult occupant. IO went through our photo albums and asked us questions about who were there at our wedding, which we answered all questions outrightly. At the end of the interview she said she will have to reschedule another interview to ask us more questions. She gave us a white paper to sign ( something about how to remove the conditional 2years green card) which we signed and gave back to her. She escorted me and my wife to the door and said we will receive a letter for the next interview, though she was very nice with us, no separation . But am just so confused and I hope u guys will give more insight about all this , thanks and waiting.
