OPKs help, did I miss my surge ?

Alexis❤ • I am 22 , married to the love of my life . We have a beautiful little boy . We have been ttc #2 for 2+years
CD 12 is the only "positive" I had but it doesn't look dark enough to be positive . I had ovulation like cramps CDs 9 and 10 . I feel like I missed my surge .
