scared of scan

an

hi all I've got an early scan next Thursday I'll be 6+1 by ovulation and I'm terrified there's nothing in there I'm deffo pregnant had 2 loads of betas with levels going from 136 at 4 weeks to 336 and 4+2 but I've got barely any symptoms and I'm really worried I'm going to go and there's just going to be an empty sac or something 😢😢
