Clear blue ovulation

So I’ve been tracking my ovulation using clear blue digital advanced and since the 22 of July I’ve been getting high fertility (flashing smiley face). But the <a href="https://play.google.com/store/apps/details?id=com.glow.android">gLow app</a> says my fertile window isn’t until the 29 🤔So yesterday I tested in the morning and I got the flashing smiley face but later on in the day I started having pains in my side and cramping so I thought let me just test to see and it came back as a solid face meaning I was ovulating. My husband and I have been using pre seed this whole week and so this morning I used another clear blue advanced because the other one will display the solid face for 24-48 hours and this morning it was a blank 0. Has any one else experienced ? Should I continue to test because I was supposed to ovulate August 3 according to glow.
