Wan to start temping

Hello everyone, well today I'm 11 dpo.. Peroid set to start on the 7 or 9th according to glow. Got the dreaded BFN today after it suggested I should take a test today. 
I feel so bummed right now, but I guess it's on to cycle 3. 
Does anyone have any suggestions when I should start temping goin in to the next cycle. Any suggestions would be helpful at this point. 
Thank you ladies in advance
