Early scan at 6 weeks 1day

Hello ladies!
I'm going to be 5 weeks tomorrow going to have an early scan next week Friday at 6 weeks 1 day.. Had a mmc in May so I'm terribly scared to go there and be told the same as back then.. Hoping they can see a baby & heart beat at that many weeks??
I've made it 5 weeks myself as clear blue says 2-3 & it was 3 weeks since my fertile window.. But lmp reckons I'm 6 weeks tomorrow it's all so strange..
Any advice would be kind :) 🙏💕 praying that this is my rainbow xx
