I am 37 years old. No children. Obese. I have PCOS. I am very irregular. At times my flow can be extremely heavy (a tampon a hour). I also always have extremely large clots all the time. Does anyone have any suggestions for what cup would best for someon in the situation I am in? Any help or advice I would really appreciate. I just done with buying tampons and pads. The cost, the irritation, the trash...I've just had enough.
