Confused.... late ovulation?

Ok ladies, this is weird to me. My cycles are 29 days, 3 day period. And I just got this, is it +, and by glow my luteal length is 14-15 days? I tested during what I thought was my fertile week and nothing. I mean I got 2 lines but not like this. And if it is +, will my period come late (hopefully not at all). This one is really throwing me off. I'm on cd 19 with expected period Jan 21.
