First ultrasound

I've got my first early ultrasound next Thursday 2nd September, but I'm worrying over nothing I'm sure, as ive got 4 healthy babies but can't help but worry there's going to be something wrong, I've had 5 losses before so 4 miscarriages before 12 weeks and a stillborn daughter at 26 weeks so I just can't relax and get it out of my head anyone else feeling the same ??
