9 weeks and worried

[Flip2018]

Hi everyone, I'm currently 10 weeks with my little one after having 1 blighted ovum miscarraige in May. I had an emergancy scan at 6 weeks and confirmed baby with a heartbeat. I am just so worried at 12 week scan that something will be wrong and won't be a heartbeat anymore. Sonographer said at 6 week scan 90% with a heartbeat are fine from there it after loosing my first pregnancy at 12 weeks the anxiety and worry is becoming more. Anyone experienced similar or having any coping tips or advice for me? Thank you
