My doctor told me I could try castor oil at 39 weeks since we are doing an all natural birth and I refuse to be induced unless he absolutely thinks it's medically necessary.. So I just took a tablespoon and gonna see how it works! Will keep you updated, I am almost completely thinned out and nearly 3cm dilated with baby at a -1 station so he said I was a good candidate for it to work. Fingers crossed! I am so ready to meet this baby!
