Help! So confused

Candi • Baby one born March 2016! Was TTC for 20 months. Baby 2 born 6/2019. TTC for 20 months. Now TTC baby #3. Scar on my tummy is from surgery I had as a baby.

Plugged in my Temps to Glow, Fertility Friend and PreMom apps (I couldn't remember the exact times I took my temp every day and I know it wasn't exactly the same time each day). Any help?? Also, I don't know why FF has me with 22 day cycle.
