Ovulation test

Talia • Wed, Mar 04 • BFP 6/29/2015. BFP 3/4/2017

Ok so my period is 5 days late all tests say not pregnant so today I decided to take an ovulation test. I use glow and ovia same info put in to both apps but always they have me ovulating on different days. Well according to glow I'm ovulating I'm beyond confused now... Been trying for almost 9 months now..
