Charged for missed appointments?

Nikki

Im in Texas where we are experiencing a lot of business and road closures along with power outages due to the weather. I have my anatomy scan tomorrow at 10:45am but I haven’t been able to get in touch with my OBGYN office. They’re phone either shuts off or the voice message system says they’re closed due to the weather. I didn’t get an email or anything saying they’re rescheduling me but my main concern is if I miss this appointment do you think I’ll get charged or get some kind of strike or anything? Idk I never miss appointments for anything so I don’t know how it works. Especially since it’s not my fault, I don’t want to get charged or something.
