My husband isn’t allowed to come to my ultrasound appointments

This is our first baby, and it took so much for us to get to this point. I have an autoimmune disorder and it took 4 years to get my body healthy enough to get pregnant. It’s heartbreaking for both of us that he can’t attend. He’s never heard the heartbeat. I’m told it’s a Scripps rule, and doctors don’t get to allow visitors. Can anyone share their experience? We’re you able to get accommodations? Recommendations for other prenatal care facilities? I’m in North County San Diego.
