Dear LK Chan,

For your simple ovarian cyst, your gynaecologist has given you appropriate advice- be reassured!

For the shortened menstrual cycles length to 24 days, it can still be normal if the pattern is relatively regular with duration of bleeding is within 7 days, no excessive flow, or intermenstrual bleeding etc. If in doubt, please check with a gynaecologist.

Hope this is helpful for you!

Best regards,
Dr Ong Yeu Theng Charas
