8 week U/S no Heartbeat

Terasia
I went in for my second U/S first one at 6 weeks was told there was a Heartbeat (seen the flicker but no audio) ... But that I have a tilted uterus that makes baby hard to find. Went in yesterday for 8 week scan and was told that there is a fetal pole but no heartbeat 😪... Devastated isn't  even the half of it. I experienced a MC in February 2016 with no heartbeat ever seen - I am praying that this Doctor is wrong!!! I am seeking a second opinion with a different facility! Prayers and any experience with this is needed. (this is 6 week scan)
