Just need to vent

My first prenatal appointment was suppose to be Wednesday, the 13th. Well Moday I got a call explaining that the Ultrasound tech wouldn't be in and asked if I wanted to reschedule the entire appointment. So we rescheduled it for Tuesday, the 18th. Fine, worked out since my husband was off that day anyways. 
Well yesterday I get yet another call. They told me they were changing it from *Friday* because the ultrasound tech would be gone. I said 'ok, but my appointment was never even set for Friday. It was originally today. They changed it to next Tuesday at 1 for the same reason.' She said 'I'm not sure who told you that, but we have you down for this Friday. You can still come but you'll have to come back for the ultrasound or we can reschedule the entire appointment.' After arguing with her for 10 minutes that I actually did know the day I was born and it wasn't what they were saying and the fact that I've never been there so I'm not sure why she has me as a repeat patient. 
I finally just said 'Honestly, this is getting ridiculous. Give me a day and let's stick with it, please. Cause I don't want to come down there and they act like I shouldn't even be there'. 
So hopefully they don't change it again. I wish I would have thought to ask her name in case they tried to. - . - 
This is our first pregnancy after our miscarriage last year, so we're super nervous already. Just ready to see the baby and know that everything's ok!
