AF Cramps followed by Pinching

[TTC74]

I’m 10 DPO. Yesterday I experienced some serious AF style cramping. I was sure AF was imminent at 9 DPO. This morning I continued to have a little cramping then it stopped completely. Tonight I’m having pinching in my uterus. Anyone else have this prior to a bfp? I’m bfn today at 10 DPO but my last baby was an 11 DPO bfp. So, latish BFPs are not uncommon for me.
