ways to bring on labour?

I'm 37 + 6 days today and for the past few days I've been having more cramps in my stomach, horrible cramps in my legs, sharp pains down below every now and then. Also I've been needing the toilet a hell of a lot more. Normally I pass a stool 1-2 times per day but over the past few days I've been going up to 8 times a day!! I'm struggling to walk also, I waddle from side to side😂 I'm in so much pain when I get up and walk around, sharp pains shooting through my hips and lower part of my back, tops of my legs also. I'm guessing this is possibly the lead up to labour (I pray it is anyway) what are some ways or old wives tales to induce labour? I don't have a clue what's true and whats not but anything is worth a try! Thankyou!
