Is anyone is the same "boat"

Jessica • My name is Jessica. I am married. We have a 9year old son and a daughter who is 2!
So my AF is supposed to show up day. It hasn't yet. All my test are showing bfn. The only symptoms I have are tender breast which happens while pregnant or AF so not sure what to think. I don't feel pregnant so maybe my AF is going to show at some point? I hope my AF shows soon so I can start a new month of ttc. Baby dust to all :)
