Ovulation help!

So since coming off birth control my cycles have been 35 days. Maybe 4 months or so. 
This month I was hoping would be the month for ttc. 
Yesterday was day 21 and I have had bleeding, first light and pink and today medium and browny colour.
What the hell is it ? I thought it might be ovulation bleeding but not now that it is brown red and heavier.
Could it still be ovulation ? Or is my period messing about ?
