What to think of this??

Kayla • Stopped depo 2-2010. Got pregnant 10-2011. Healthy birth 7-2012. This time: stopped depo 3-2014. Waiting for BFP:)
Good possibility of pregnancy? Due to start period on cd24 which would or could be 12dpo. I'm on cd20 and 8dpo.
Anyone else have similar charts and want to share?
