Been trying for 3 yrs

Hey ladies 
I need a little help staying positive today. I am currently 9dpo and just received another bfn! My husband is pretty disappointed because I have been having some major symptoms and we both totally thought this was our month. My period is due August 7. I know I am not out until af shows up. How many dpo were when you received your bfp? And how long had you been trying? 
Thanks in advance! 
Baby dust to all!!
