Ovulation bleeding help please?

So three then two days before my period I had a pinkish coloured discharge. To my knowledge I have never had ovulation bleeding but from what I have read it seems to be the case but I do not have a straight yes or no answer. I was really hopeful that I might conceive this month, but glow said I hadn’t ovulated then and it was on CD 10 and 11 so I don’t know what the chances are? I’d be delighted to have any information on ovulation bleeding. Thanks
