I can certainly understand the wish to induce labor and get things going, but even natural DIY induction methods are not guaranteed to work. I gave birth unassisted to my third child a month ago and when I delivered him I was 43 weeks and 2 days pregnant. I had tried castor oil a week before with no results (well yes, I spent a lot of time in the bathroom and had some contractions that went nowhere), and sex (doggie-style since you get the sperm closest to your cervix that way). Neither worked even though I was very far along.
In the end my son weighed only 7 lbs 10 oz which is average size and surprised us (we thought we would be much bigger). Next time I will definitely just wait the baby out. Nothing will happen to you when you go past your due date. Your baby is fine in the uterus and labor will start whenever you are ready.
By the way, you are not really late until you go past 42 weeks (most births happen between 38 and 42). But every baby and every pregnancy is different. Some just "cook" longer and there is nothing wrong with that.
That said, other methods I had heard but did not try are: spicy foods (which probably won't work if castor oil doesn't since the premise is the same: to irritate your bowels), accupressure (there are pressure points that are supposed to help induce labor: webbing between your thumb and index finger and one on your lower leg), Primrose oil (supposed to get the cervix ready, taken either orally or vaginally).
I wish you all the best with your pregnancy and hope you are more patient than me. Try to distract yourself by planning an activity that gets you out of the house every day. Your baby will come. Until then try to enjoy him or her where he is.
