Confused by ovulation date change HELP!

Brittny • 1 1/2 yr old
My expected fertile time was july3-7 I took ovulation test the 8-11 with it coming back negative ( I just started opk for the first time so didn't start right away) on July 10-14 I had light to medium sticky- White CM now today just for the heck of it I took another opk test and it came back positive still some creamy CM but very wet as well 
​( almost like I wet myself lol)
​Next MP scheduled for early next week. Could I really be ovulating this late or could it be pregnancy
