weirdo ovulation - TMI warning

I have had my period back since March this year and it has gone pretty normal, usually 26 days with the odd long cycle. However the last three cycles have been a bit strange. I have my period which is heavy and lasts maybe 4-5 days then nothing for a couple of days then I start to get a brownish discharge like old blood mixed with creamy CM about day 8-9 just before ovulation. I am also getting crampy feelings, kinda like AF is here lol! Then I seem to be ovulating on about day 10.
Is kinda odd I think...does anyone else have this bleeding thing...

Maybe it's the more liquid CM "washing down" the last of your AF? Not really sure but it may be best to talk to your Dr esp if it's concerning.
