Nipple stimulation for inducing

So ive read this is one of the most effective methods. Did it work for you? If so how long did it take. Ive done it once but was considering doing it again. Im having contractions every 3-5minutes lasting 45-60 seconds each. But still mild intensity. Im dialated to 3cm as of my last check about a week ago.   Babys engaged and i feel like her head is between my legs when i walk.(SO UNCOMFORTABLE)  Im assuming my body is ready but want to kickstart things.  Should i give it another try and what method works best?
