When am I ovulating?

Kendra • Wife and mother❤
Have been trying to conceive with my husband for 6 months now and have been having a few signs this past week or two. Not sure if I missed my period last week as it was only three days of very light pink spotting. Juat took a test. (Pics below) don't think I'm seeing a line...but the only thing we are not doing to conceive is tracking my ovulation day. How do I find this out? Thanks
