Firstly be thankful you have been able to carry your child this far!
A full term pregnancy is 40 weeks, i'm sorry you feel you have to rush this.

The safest way is walking - yup just walk and walk. Most "remedies" are actually dangerous to you and your child.

If you really can't bear it get and see your doctor.

I know a few people who on their due date or few days later, ate a really hot curry, and that night they went into labour. Try that.
Goodluck
