Petrified of labour

This is my first child I’m nearly 28 weeks pregnant and have read up on lots of things to do with labour. However today for some unknown reason I’ve woke up in this bubble of extreme anxiety about labour and the pain. All that’s going through my head is what if my partners at work and I can’t reach him, what if I can’t manage the contraction pains what if I just don’t have a clue what to do the day it comes… like I’m absolutely petrified of it and I don’t know if it’s due to coming up to my third trimester.

Did anyone else have these fears and anxiety and just not looking forward to it apart from having the baby here?
