Hello and welcome to HCM,
Your history suggests that you are having long menstrual cycles and long duration of menstrual cycles.
In this condition, an endometrial biopsy/ curetting needs to be done.
This test will identify if there is any abnormality in the endometrium (lining of uterus
These symptoms are not characteristic of PCOS
PCOS is poly-cystic ovarian syndrome is characterized by multiple follicles in the ovary none of which matures up in the menstrual cycle.
This abnormality of menstrual cycle and absence of ovulation can cause menstrual irregularities and abnormalities.
There are a couple of other investigations which need to be done to confirm or rule out PCOS.
So, consult your gynecologist for clinical examination, investigations and appropriate management.
Thanks and take care
