Pos/Neg Ovulation test?

Michele • Married to HS sweetheart-TTC #1, 3 failed IUIs, IVF#1 miscarriage 11 weeks, IVF#2 miscarriage 6 weeks, IVF#3?
I took an ovulation test at 3PM that was clearly negative. Decided to take one just now for the heck of it and I really can't decide if it's positive or negative. I feel like the test line could be a little darker, so I'm leaning more towards negative and thinking maybe tomorrow will give me a definite positive. What do you guys think?
