Do I have to many ovulation fertility apps??

SC
I have PCOS, I'm taking clomid and Metformin 1000. I have Glow, Ovia, Life Cycle, Fertility Friend and another menstrual calander to track my Big O and fertile days. I think I'm driving myself crazy because each one have different fertility days. They off by a day or two but Glow has my ovulation two weeks from today and the others have me ovulating this week. I'm so confused.. Have anyone experience this??? Should I get rid of some if so which one?? I think this is the problem and why I haven't gotten my BFP. HELP ?
​PS. I'm not sure what group to out this in so I choose general TTC. Thank you
