Nervous for first u/s

Just need to vent a little, I'm 10+5 weeks and going for my first ultrasound on Tuesday, I'm so nervous as I've had 3 miscarriages (last one a year ago) I'm scared and hope this bub is doing okay!

Not had the best track record my son was born 3 months early and my daughter was 6 weeks early has anyone else been in a similar situation? I'm almost so chicken that I want to cancel the scan lol
