A Month in the Life of a Cervix
Very nice pictures of a cervix throughout a 33-day cycle.
A word of advice. Because the speculum insertion angle varies from day to day, the best way to orient yourself is to start with Day 29 and use that as your point of reference:
You are looking more or less straight down the vaginal canal. The speculum blades are on top (anterior) and bottom (posterior). On both sides (lateral) you have the somewhat collapsed vaginal wall. Now, notice how the cervix is pointing upward. That's because the uterus is most likely on a downward axis (retroverted). This is just a normal anatomical variant; something like this:
/ body of uterus
I also want you to notice the nice pics of the cervical mucus. [Your word for today is: Spinnbarkeit.]
EDA: Pic problem corrected.
