Naturally Inducing Labor [maybe TMI]

I just had my 39 week appointment today and finally got a cervix check... CLOSED! My midwife said that she barely got her fingertip in. So, she asked about our thoughts on inducing labor and we'd like to go as natural as possible for as long as possible. I didn't really want to do things to jump start the process such as sex, extra walking/exercise, evening primrose oil, and raspberry leaf tea, but i guess we're going to go that route to avoid medical intervention... Wish us luck!
