okay, in horses you can predict foaling within 12 hours by measuring the amount of calcium and magnesium in their colostrum. with dogs, you can predict their birth withing 2 hours by monitoring their basal body temp. dont you think there is probably something like that with humans? i wouldnt be suprised if our BBT dropped 1/2 degree the day before labor begins . im gonna chart to find out! what do you all think?
