A small point.

I believe that I have just experienced the American-English vs. Other English great language divide at full force.

At least I hope I have, or you’re all placing the progesterone in a rather non-standard locale.

I expect the problem is one similar to the thongs vs. thongs (flipflops vs. anal flossing underwear) confusion. You mean one thing, and I another, when we both say ’suppository’.

With the aid of simple diagrams, I hope to confirm that we both intend the same destination for the progesterone and restore my bug-eyed surprise at reading ’suppository’ in the comments field so many times.

This is my understanding of a suppository:

 

In case the snapping on of rubber gloves doesn’t have implications for some of you, I’ll be less obtuse. 

Removing all lingering confusions, this is a suppository:

So you can, quite easily, imagine my bemusement at reading what seemed like all those references to anal progesterone application. The first clue that something was, well, up was that you all seemed to happy to discuss it and in my experience people are reticent to talk about what (if anything) goes up their butts. Even when they’re red-faced in the Emergency Department trying to explain just how the carrot got there.

This is my understanding of a pessary (and what I assumed you all meant with suppository):

 

Different hole entirely!

Glad we cleared that up before I wondered if I was doing something wrong.
