12 dpo bfn ... ugh

We’ve been trying for 10 months and this is most likely our last month trying for a while as we are financially tapped 😞 I’m having a ton of symptoms that aren’t typical for my cycle yet all I’m seeing is one line. This is soooo disappointing. Any ladies got a bfp later than 12 dpo? Af is due In 2 days... how do you ladies cope with the tww and disappointment before you get your bfp?
