When should I continue buying baby things we need after baby shower?

Ka
Hi everyone, I had my baby shower yesterday afternoon. It was lovely but I did get a bit stressed toward the end! I didn't have time to open gifts until I was at home. We didn't really get things from our registry so now I'm wondering when can I start getting more? Buy buy baby gives me coupons for 20% off but of course they expire. I have two that expire today. How long did you all wait after baby shower? I guess I'm in mommy mode for sure now especially after yesterday. I'm going on 34 weeks. Had an early-ish baby shower because I wanted to be prepared due to never knowing what can happen.
