Ovulation???? Confused! Help!

Hannah • Will be trying for baby number 2 soon!
The top 2 test are test from fertile window days 1-2 and then the bottom 2 are yesterday and today's. Fertile window days 3-4. Yesterday all I had for pregnancy chance was 15% and I thought maybe it was negative till I took today's test....27% chance today. Is the third test on the pic positive or negative?
