For my first, the day i wanted to go into labor, I drank aloe vera juice, did a ton of yoga, got a pedicure and did probably 15 things they tell you not to do when pregnant because they "could induce early labor". I went into labor that night!
Do I have to ask my dr about drinking the promrose oil? Or is it safe to drink it? Because I heard a lot bad stuff on castor oil. And I can drink it orally right? Does it start contractions right away?
Drink red raspberry leaf tea, and get primrose oil supplements.
Its helps soften the cervix and thus induce labor.
Also, check with your OB or midwife to see if they can recommend any herbs.
Walking, exercise ball, sex helps too.
Good luck!
