Devastated

Went in today for my 8 wk 5 day ultrasound to my avail it was just a sac😪 I Believe in god and perfect timing a week before this ultrasound I was sent to have an ultrasound done with a private doctor which they seen and myself to a sac with yolk and a lil circle. I’m just flabbergasted that they didn’t try and do more she just said I was probably earlier then expected and having me come back in two weeks. Has Anyone Ever Been Through this. IT SUCKKSSS Which I’m so Keeping my guards up but don’t wanna be let down in two weeks when I go back and NOTHING AGAIN🤦🏽‍♀️😩
