Hmmm???

Okay, I’ve been using the Easy@Home ovulation testing strips and app, pretty cool, however; my peak day was the 6th of March and the app gave me a reading of 176 and today I got a reading of high and 52. The test and control is pretty close in color, I would say almost the same color. This is making me wonder what the heck is going on. I’ve already ovulated so I should have went down and stayed on the low side, not shoot back up. Anyone else have this happen? It hasn’t happened the last two months with these testing strips.
