14DPO, no af, bfn

So frustrating. I had mild cramping for a few days leading up to yesterday and today I have none. My breasts have also been super sore the past few days and are still today. Bfn with this mornings FMU. And no period at all. Anyone have any experience with this and get a bfn at 14DPO and then end up getting a bfp a few days later?? I could really use some encouraging stories right now 🥺
