Another BFN

I'm so heartbroken. I tested today at 12dpo. AF is due in 3 days. I thought I had pregnancy symptoms. I had really bad cramping about a week ago that I thought was implantation cramping but I was obviously wrong. My breasts are sore to touch. And I have a minor yeast infection which isn't normal for me. I know there's still hope but I'm convinced I'm out this month. I cried after I tested. This is our 6 month of TTC. 😔
