Have I ovulated I’m confused ?

Jade

So this is my first month properly tracking my ovulation. We have been trying for a while but figured since my cycles are pretty irregular lately it would be easier to know when I ovulate and this will also help me with knowing if my period is late or not. However I’m confused is it normal to get a day when it’s super dark than the others and the back to normal the next day would you say it’s just a janky test? The lines are definitely getting darker and I don’t think I’ve ovulated yet which would be normal this late for me but thought it weird that one seemed pretty dark we bd’d last night so super hoping to catch my window
