Should I keep my appointment or move it three weeks?

Hi all, my anatomy scan was supposed to be last week but it had to be pushed back a week to this Thursday because my OB was out of the office that day. I came down with a cold two days ago. I tested negative for covid. My OB office requires masks. I went to reschedule my appointment and they don’t have anything till the end of may and I’ll be 23 weeks at that point, which I thought is a little outside the window of when you should do the anatomy scan. Do I just take the 23 week appointment or do I go with a cold? I’m not coughing uncontrollably or have a super runny nose or anything but I don’t want to be an asshole.
