Pregnancy announcement issue

So I’m currently 11+4 and we were hoping to make our public announcement to next week after our 12 week appointment (and if it goes well). My 12 week appointment is scheduled to be a pelvic exam. I do not believe they will do an ultrasound. We wanted to take announcement photos this weekend, but only have photos from our first ultrasound to include with our pictures (first ultrasound was at 7 weeks and 3 days: baby is so small in the pictures!) so we just use the early on ultrasound photos with our pictures we take? Should we try to wait longer until our next ultrasound (not sure when that will be yet). I was really hoping to announce soon but don’t want to look silly with early on images.

Below are examples of our ultrasound images
