ovulation

I'm getting so concerned now.. I'm been TTC for over a year I'm 22 and nothing at all. 
I've been taking ovulation test this month to see when I ovulate. I have read normally cycle day 12-14.. I'm on day 15 now and my ovulation testing line is still light purple. 
Am I even ovulating.. 
Can someone share something possitive I'm getting to the stage of something is wrong with me as it seems everyone my age pops kids out with ease:/
