You can also find it in Week 31 of the I'm Expecting app. Good luck!
A friend told me she used it starting her 38 week and she said her labor went smooth that she didn't even get an epidural that she pushed for literally 5 minutes. But with me I didn't use anything with my son and was in labor for 16 hours which 3 of those were pushing and it got to the point that the doctor ended up cutting me bc I couldn't get my sons head out. But I'm currently 36 weeks today and will start using the oil pills next week. Hopefully it helps this time as I don't want to tear or get cut.
