Adjustment of Status - I-485

Me and my husband had the interview on May 14th. And I think the interview went well and the officer was having more of a conversation with us, rather then asking us questions. However, It's been more than 3 weeks and I have not heard anything back. My case status online is stuck at Interview was scheduled and case has been received. There is no information that the interview was completed and that it might be under review. I tried calling USCIS but the person on the phone was not very helpful, and all was able to tell me was that the case is under normal processing time. The officer wrote on my passport the case I-485 was pending and she kept my updated Medical Report.

I'd love to hear your feedback, and if you think the case is not being processed normally. I hear people getting approved the same day, and receiving the green card in a week and I am very worried.
