Ultrasounds

So I am 13 weeks pregnant, my last appointment was a month ago and I went in today and all they did was blood work and checked if baby had a heartbeat. Was happy baby was okay but I was confused as to why I didn’t get an ultrasound? With my first pregnancy I got an ultrasound every two weeks even early on. And so when we went to leave I scheduled another appointment from a month from now which is February 10th and the Lady told me that I won’t be getting an ultrasound done during that appointment either. I will be 18 weeks by then and I’ve only gotten one ultrasound done this entire pregnancy, is that normal?? I just sad bc even if I heard the babies heart rate I didn’t get to see him/her ??? I feel like am missing out on pregnancy milestones because I had a lot of ultrasounds with my first pregnancy.
