Hello,
Welcome to ehealthforum and thanks for writing
Pain in the left abdomen can be due to various reasons as pelvic infection,ovarian cyst,cervicitis etc.Normally the ovaries are attached to uterus only so that is not a cause of concern.
Regarding the spotting if it has been more than 6 weeks of ligation and bleeding/spotting is persistent then it requires an evaluation as any sudden changes in the menstrual cycle is not expected.
It is difficult to comment here without proper examination.Kindly consider visiting your Ob/Gyn for detailed evaluation.
Take care!
