Bummed out and emotional

My OBGYN office is very busy I had an appt. schedule for Dec. 27th, they called and had to cancel my appt. due to accidentally scheduling me on my doctor's surgery day. So I take the next appt. avaliable Dec. 31st. they called me Friday and rescheduled due to an emergency surgery that is needing to be done that day. I am understanding that things happen and I hope all is well for person needing the surgery. I'm just so bummed I have to wait until Jan. 3rd for my appt. I really hope they dont have to reschedule again. Both appts. they rescheduled me for are work in appts. so I'm not confident this one will actually be kept. I also asked to see a different provider since her schedule is typically booked out a month or two in advance, it's not a option as I am high risk and my provider is the only high risk ob at the office. I'm sure im just being whinnyand emotional, but I needed to vent somewhere. I'll be 12wks on Monday and just want so badly to see our baby.
