hi, i have been experiencing bloody discharge since cycle day 15 and am now on cycle day 24 It has progressed from being scant and pale pink to dark brown almost black more clumpy discharge. On cycle day 12 i had a small amount of bright red/pink watery blood when wiping with tissue paper upon waking. I am currently trying to conceive but my periods have become less regular over the last few months. I have done a pregnancy test today (CD 24) but it is negative. According to an ovulation test I ovulated around Cycle day 11. Any ideas what the bloody discharge might be?
