My cycles have become shorter, ovulating on cd10

Lyanna

Hi everyone I am 35.5 years old, mom of two. My menstrual cycles have become shorter they are 25-26 days. Earlier they used to be 28-29 days. I am ovulating too soon. What could be the reason? Am i having early menopausal symptoms? I feel like I am just not getting enough rest between periods they keep coming quickly😒

Also want to add that I still have a heavy flow first 2 days so periods are not lighter, just quicker.
