What are the Causes of Irregular Menstrual Cycle?
Many variables can affect the length and timing of your menstrual cycle. Some are manageable while others may link to other medical conditions. Causes may include:

- Pelvic inflammatory disease. It is an inflammation of the female reproductive system due to sexually transmitted infections.
- Perimenopause. Entering the transition period may affect your period. Your menstrual cycles will become erratic as part of the process. If you skip more than two periods, you are probably in late perimenopause.
