I am so scared for my scan tomorrow

I go for a scan tomorrow I should be 7 weeks 3 days but just can’t shake the feeling that something going to go wrong (had a miscarriage at 6 weeks in October)

I keep getting these taught that the embryo stoped growing and that it is a blight ovm I am so scared as this was my last round on fertility medication for a year.

How do people deal with this worry 8 am tomorrow can’t come quick enough and not even 11am the day before.

I had a scan at 5+3 and wasn’t this nervous or scared 😟

UPDATE: baby was seen and heartbeat was perfect
