Scared of labour.

Hiya, don't know if I've posted in the right page here. I am only 9+4 weeks pregnant, this is my 3rd but I'm absolutely scared of labour this time even though I've got ages to go. I'm scared because with my last child there was mild shoulder dystocia, she was only 7lbs 14oz which is 2lbs bigger than my first, and they said it was cause I'm not used to having a bigger baby. Every time I remember her birth it brings it all back and worries me an awful lot. What will happen this pregnancy? Will I be under consultant care? Will I have more growth scans (had a few with my girls). What are my chances of a Csec this time around? Sorry about all the questions I'm just so terrified.
