Irregukar cycle/spotting after miscarriage

Good day po, meron din ba dito nakaranas ng light bleeding/spotting after miscarriage? Nakunan ako nung May 2weeks ako dinugo nun tapos after 3 weeks dinugo ako kaso di gaya ng normal na menstruation parang spotting to light bleeding lang tapos on and off. Normal naman cycle ko before ako napregnant. Na.diagnose din ako PCOS nung pag.confirm na wala na si baby. Thanks.
