Oh that's a possibility! Female health is still so hush hush even with about half of all people experiencing periods. Anytime moods change it stands to reason that fluency would change. I had a medical experience where my period was relevant in a non-reproductive context and the most relevant specialist sent me to a reproductive specialist seemingly just to talk about my period because he had no comments. The second specialist evaluated my cycle but could not speak at all on the more pertinent medical issue: told me that was the first doctor's wheelhouse! I got some treatment but still a lot of unanswered questions, I wonder often if males have totally routine health issues they bring up and their doctor all but escapes under the exam room door lol
