You get used to blaming things on your cycle I think.
After 40 years of a 28 day cycle I had a number of niggling little symptoms that were clearly affected if not cause by hormonal fluctuations. The spots that appeared every month for 2 or 3 days, the bloating and other classic PMS things. I used to get joint pain in my fingers every month for 2 days.
Most of these have blessedly disappeared but a few pop up now and then which makes me wonder?
