Can you spot brown 3 day after bbt dip?

[Elle_A]

I had a temp dip that went slightly below the coverline at 6 DPO and today (9 DPO) I had light brown cm when I wiped once. If that bbt dip was implantation is it possible to have brown spotting 3 days later? Maybe I missed spotting after the dip. My symptoms during this TWW has been silent reflux, cramping from 7 DPO until now (unusual), emotional and mood swings at 8 DPO (unusual), and a constant dull ache in my lower abdomen that sometimes radiates to my back (unusual for this point in my LP). My luteal phase is usually 10-11 days long should I still have hope? Thank you!
