I found these online. I'm 90% certain I have low progesterone (I was even told so by a doctor years ago). I've been in talks with my doctor recently about a few issues I've been experiencing, and her solutions are very severe and invasive. I plan to try these test strips as a way to prove to her that it's mainly progesterone issues and that maybe a progesterone supplement might be the way to go, or at least worth a try. So, for anyone out there who wants to maybe confirm ovulation, or dealing with something like me, here are some test strips I found.
