Who do i trust Ovufriend or Fertility Friend Re O?

[OhTheJoy]

Fertility friend says i ovulated on CD20 (BD the day before and 3 days before)

Ovufriend says i ovulated on CD21 (so BD would be 2 days before and 4 days before)

Which one do i trust?

Ive used fertility friend to monitor my periods for 2 years now (during NTNP) but this is my first cycle using BBT.
Ive never used ovufriend before until this month.

Ive put the same info in both, i know its only a day apart but it would mean we BD at the wrong time.

Who would you trust?

My charts are in my signatures if you want to have a look.

Thanks

Ff. Your firat rise after that dip is higher than previous six temps.. which means o

Cheers! i just looked and thought it was odd that ovufriend says i ovulated with elevated temps and above the cross line :/

I will stick with FF from now on, think i will delete my OF account, but i will message them before i do

my ovu and ff match so i dont think you should delete it as its only a day difference
