Irritated

So I was supposed to have my 18 week ultrasound & follow up appointment at 2:30 today. My husband and I took the day off from work because we were away all weekend and both had the days to use, so we figured we'd just relax and go to the appointment together. It's been snowing all day so we were planning on leaving early. About 10 minutes before we were going to leave I got a call from the doctor's office CANCELLING and having to reschedule because the doctor is at the hospital for deliveries and the ultrasound tech can't do the u/s if the doctor isn't in the office.

I literally started crying. I'm been looking forward to this for so long and I'm annoyed I need to wait another 2 days. I feel like taking today off was a today waste and I'm just really upset and irritating. I just want to see my baby and be reassure everything is going well!
