What wives tales have u tried- any work?

Kristin
I am 38 weeks, 4cm dilated and fully effaced- (I think I still have my mucus plug)however no real contractions or anything.Today just felt like trying everything I could -almost anything-
I took prim rose oil orally, with raspberry leaf tea
I bounced on the birth ball while stimulating my nipples 
For lunch I had tacos with very spicy salsa
- didn't get heart burn
Went on a long walk up this hard hill in my neighborhood- didn't get contractions but I got pains in my groin
Sigh::: now I'm just exhausted will keep everyone posted -
Please post what you've tried and results
