TTC: Fertility Problems?

I have 2 <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period tracker</a> apps, this one & PeriodTracker Deluxe. They both say the 25th thru the 28th I'm fertile ( of this month ). I took ClearBlue Advanced digital ovulation test yesterday and this morning but they are coming back as not fertile? I stopped taking birth control about 2 weeks ago.

I checked and my body is creating discharge.

Am I just really not fertile? I'm so confused.

any inputs/advice would help greatly. :)
