Need help please

Michelle🐶 • 31, happy married, 5 angel babies, still trying for first human child - already have my pitbull fur baby!!
Ok, so for the past 3 months each time I used my Clear blue difital ovulation kit the first day I would test and get a negative and the next day it would be a peak result. I figured it was due to being in my window.
 I thought about it this month because my week should be next week yet this morning it read peak. I went out and got a first response test, and that is reading negative. 
Which do I go by? I can't log both tests and I'm not sure if maybe my clear blue is too old or if because the first response was in the afternoon it's not reading the surge correctly. 
I just want to know because my husband is away until Sun and don't want to miss the week.
