I heard if u use a breast pump now that it can put off hormones and make u go into labor is it true

Yes that is true

No, I tried it to induce labor and nothing happened

one of my friends was telling me bout it but i didn't know if it was true or not cause I am due tomorrow and I am desperate to have my baby girl I have been walking everyday and night

Potentially, yes.

It causes stimulation which causes your uterus to contact.
