Ovulation Question

Katie • My name is Kate and I just gave birth to our beautiful daughter February 17th 2016. She is our world and we couldn`t feel anymore blessed❤ I am currently pregnant with our July 2018 baby!

So CD 12 at top was yesterday and today is CD13. I know CD 13 is positive but, my question is does this mean Im ovulating now or is it more likely to occur in the next two days? If I take a test tomorrow and its getting lighter does that mean I ovulated? I didnt temp this month as my 1.5 year old has been teething and wake times are all over.
