Doctor won’t let my fiancé come!

So I have my first OB appointment tomorrow, we have to do a video call due to the coronavirus. When they called me to tell me I could do my bloodwork today (probably so it’s all set tomorrow for my appointment), I had asked the receptionist for my fiancé to come with me for our baby’s first ultrasound appointment. I’m exactly 6 weeks today so I know in a week or so we’ll be able to hear the baby’s heartbeat and I know for a FACT that we will hear it at the first ultrasound! Anyways, so I asked the receptionist and she literally tells me “no, you have to come alone”. I’m sorry what?! My fiancé, the FATHER of OUR first child can’t come in to MY ultrasound appointment because of this virus bullshit?! I understand I’m a bit hormonal and that the virus is a serious this especially for pregnant women but that’s beyond unfair to me and takes away MY right! My mom works for a doctors office so she brought me home some masks to wear like literally I will make my fiancé wear a mask, gloves & even a damn hazmat suit if needed! All I know is I’m VERY unhappy & highly upset with this OBGYN office now due to this issue and I can’t get over it. Can someone please tell me I’m not crazy and that this is wrong of them to do this?! What’s your opinion???
