Hi I Had A Ovarian Cystosomy 6th October. Had My

Hi I had a ovarian cystosomy 6th October. Had my period as planned as I stopped taking pill on the 4th October. 4 days later taken back in for as I had a light anaerobic growth. Long process to get that sorted. Started bleeding dark brown including stringy bits from the 27th October continued until the 3rd November and now its bright red. Used 11 pads yesterday. I'd say it's quite a quantity and bits are in the bottom of the toilet bowl! Should I be concerned? I'm seeing the specialist nurse on Wednesday.
