Really worried

My first US is Friday, went 2 weeks ago and done ultrasound. They found yolk sac and fetal pole but no heart beat, my primary doctor ordered a US for this and called and said it looked like I would be miscarrying, went to my OB the day after and she said she wouldn’t do a US because I might be to early to find a heartbeat, they ran my hcg levels, I’ll post them below, told me not to worry but they should’ve seen a HB but not necessarily . But now that it’s coming closer to time to find out. I’m really starting to worry, I just had a MC June 30th and I’m praying that nothing is wrong with this baby. My heart will be truly shattered, what do you guys think?
