ovulation date change

Kristen
I'm so mad right now! Glow just changed my ovulation by a day because my clearblue ovulation kits said I was low today! Well my SO and I believe in the every other day method so we started Monday because they said that Friday was our peak day so I we just did the BD today and I saw how it changed so now I'm not sure if we should skip Friday and do the BD in Saturday or keep with Friday?! Thoughts?
