So mad!

So my Ob office scheduled our Ob appointment, blood work and ultrasound for today. They told me 1pm, they called yesterday and confirmed 1pm... my appointment card said 11am. I showed up at 1pm and they said my appointment was at 930... there was no way I wouldve made it to that appointment... to say the least they seriously messed up somewhere..no big deal except that they cant see me now till June 6th.... they have also drug their feet in getting me in to be seen... so I'm now missing out on my nuchal translucency scan, I will be 15 weeks bu time they see me.. this worries me, and I will also miss out on the early gender party of my materni blood test be cause by 15 weeks you are more able to see on ultrasound and even if we did blood by then the results would come back by time I was 17 weeks again can tell with ultrasound... today has been a crap shoot day... so much disappointment at once. :(

I have a sneak peek kit for gender i could have done but so scared it will be wrong because of what I have read for boy results being wrong alot... Idk what to do. Was so excited to take advantage of the new technology...
