How will I know? Back pain or labour starting?!

[firstbaby2017]

Hi all, looking for some advice and reassurance really!
I'm 40 weeks with my first and everything I feel is making me wonder 'could it be starting?!'...
I had back pain throughout the night when I woke up and have had it all morning. It hasn't eased much but gets worse at points. I have been having period like pains on and off for over a week and lower back pains but not like today!
I haven't lost my plug or my waters haven't broken so should I wait until that happens to call the midwives or should I call just to query.
Did any of your labours start like this or does it sound like a false alarm? lol. Thank-you!

If it were me I'd just wait and see. It'll soon become obvious if it's labour.

You wait. Once it's definitely labour you won't miss it. You don't need to do anything except chill out at home until you're having regular contractions you can't talk through anyway.
