Why isn't this invented?!

Why, why, why don't they have something they can give pregnant women at 40wks to induce labor gradually & naturally at home.

There are so many 'natural' induction methods that we do on our own like yoga balls and pineapple but none of them are tested or proven.

WHY can't doctors/science make a pill that will gradually prepare our bodies for labor while we relax at home over the course of a few days?!!

Why is the only induction method that doctor's provide abrasive, rushed, painful, & synthetic and in a hospital setting. I feel like medicine these days is decades behind where it should be.
