​I'm having a progesterone test in a few weeks because I have really irregualr periods. I'm also concerned about Pcos because the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> has notified me of the possibility. and was curious if the progesterone test could reveal this. I'll mention something to the nurse when I go, but wanted to see if anyone had any insight.
