TTC new to ovulation kits...

Glorya
So I have been taking a test once or twice a day for almost a month (note my cycle can range from 28 days to 42), before I was diagnosed with celiac disease and before going completely gluten free, my cycles came any where from every 2 months to every 6 months if that, so to have one that is semi regular is awesome. My son who is 10 almost 11, was a surprise and long story short I was told I would never have kids. He was the ultimate surprise and I wasn't obviously trying then to get pregnant. Now I am married to an amazing man (not my son's father) and we want to have a baby and so this is my first time using ovulation tests. All month they have been super light lines and today I took this picture. The bottom 3 are from today. 
I know the instructions say has to be darker than the control line but my question is am I close to my peak day??
Thank you! :-)
