Should I Test?

Hey y’all! So I had my peak/positive opk on Sunday 7/24 I tested that morning and it was bold and positive then when I tested again that evening it was slightly faded and then the next day it was absolutely negative. I’ve noticed little symptoms here and there. Like my sense of smell has been slightly heighten, I’ve been constipated for the last week and a half, slightly more fatigued than usual, I’ve had slight cramps here and there. I do follow two period tracking apps Glow and Flo, glow has been more accurate with my ovulation dates and period. I say that because according to Glow as of today I am 3 days late. But the Flo app has my period start date as tomorrow, but my last ovulation cycle was also off by a few days on Flo. So should I wait a few more days or go ahead and take a test?
