bbt and ovulation

My husband and I have been ttc for 7 cycles now. Fingers crossed this is the cycle for us. This will be my second cycle temping and would lime any insight. I'm worried that I'm actually ovulating too early. AF always comes between 28-32 days, but I don't think when/if ovulation occurs affects that and vice versa. I'm missing some temps at the end of the cycle as I had a vfl blue dye positive and negatives on all other follow ups so I was a bit crushed when AF showed up.
