Braxton hicks or early labour ?

Had tightenings last night started timing but then tried to get some sleep as i assumed they were just more painful Brixton hicks 🤷🏻‍♀️

Tightenings now waking me up and their more of a period pain waves tonight and a full back ace rather than when I have Braxton hicks it’s only the top of my belly that goes hard normally , but these are more in the bottom where you’d get period pains if that makes sense 🙈

I’ve tried going to the toilet and swapping sides in bed and their still there could it be the start of early labour ? Or could they be just painfull Braxton hicks now I’m towards the end of my pregnancy nearly ?

36weeks+6

3rd baby but been induced with the other two so don’t actually know what going into labour myself feels like 🙈

Thankyou in advance !
