Expert Q & A Answers About changing menstrual cycles
I am a 37-year-old female and my menstrual cycles are usually 28-29 days. But for the last three months, they’ve been about 30-31 days long. Most recently, my last cycle was only 23 days. I haven't had sexual intercourse lately, but I did take a couple of home pregnancy tests just to be sure, and they were all negative. What can be causing my menstrual cycles to be longer and then really short?
