Confused...??

Someone want to elaborate on this? Why I didn't even get a peak, just low and negative, and when it did get higher just dropped back down... And so soon in my cycle too. Normally it's 15 and 16 it happens (in April and May when I tested last). I'm still new to this. Something tells me I either ovulated early but not strong enough for it to show up, I didn't ovulate at all or I did it inaccurately. I have been using the second or third pee of the day and I don't drink enough as it is to reduce my fluid intake.
