My sister is a vet tech. She told me over the weekend that one of the ways they watch for labor in animals is by checking the animal's temp. There is a significant drop in an animals temperature 24 hours before birth. I asked my midwife about this on Monday but she said she has never heard of this.
In the meantime i have been researching the hormone shifts of labor, mainly Progesterone because that is such a 'hot' hormone and it is high during pregnancy. If any one here ever charted their temps during their cycles you've seen the upward temp shift caused by Progesterone at ovulation and the second shift at pregnancy. Well from what I have read during pregnancy Progesterone inhibits uterine contractions and keeps the cervix long and closed. It drops before labor and estrogens rise! That is the perfect scenario for a temperature drop.
I started taking my temps 3 mornings ago. I was 98.8, 98.4, and today I was 97.2. If anyone wants to start watching their temps with me I think that would be really cool!!!
You would think after centuries of women giving birth someone would have picked up on this phenomenaby now... So maybe I am totally wrong in my hypothesis. I am very curious though!
