Help so stressed out 😭😩

I need suggestions or someone’s experience from anyone who lives in North Carolina and went to Ashley’s women’s center. Or just what I should do from anyone in general. My situation is really stressful rn. I’m half way through this pregnancy and I’ve been going to Ashley’s women’s center. I’m supposed to have my anatomy scan and the ultra technicians schedule is filled up the next two weeks. They called and changed my apt already it wasn’t supposed to be til weds day now it’s Tuesday. I can’t drive right now and I live in kings mountain there’s no transportation besides your own vehicle. At the time I told them it was ok to change it. But then my hubby got a new job and he was told he can’t miss any training whatever since it’s at a security job. I called them and said things came up I can’t make it this time. The front desk told me they can’t go past 21 weeks and their booked the next two weeks. I told her if my husband can’t take me what can I do and all she said Is to be honest I don’t know. I don’t want to miss this apt. Because it’s something that has to be done but they won’t let me reschedule. Can they do even do this?? I would at least think they would of helped. Especially since it’s the only apt I can’t make it to because of timing . If the job says no should I just call my docter and see what he can do ?? Like I’m beyond stressed and there’s no other good OBs that I know of and we’ve been here a month and I have no other way out to my apt besides my hubby or my grandma who is coming back into town the same time as my apt. Still working on my license and there’s no taxis and my husband isn’t comfortable with that even if there was and there’s no Uber’s like I’m stressed beyond the point of knowing what to do
