Fertility Friend?

FF says my temps are "unstable". How does my chart look? I am aware that my cycle is not yet over. I'm concerned I am not ovulating as my last 2 cycles have been 39 days opposed to 31 and I have had fertile CM 2× in each of the 2 39 day cycles. I'm so down in the dumps and lost. This is my first cycle temping. Thanks! I also noticed my temp rises with my period. I have been temping at the same time each day.
