What is this

I woke up earlier than my husband did this morning, which is rare, he is the early bird and I am that lazy bum...but I had a very uneasy night, dreams after dreams...as soon as I opened my eyes, I felt a period like cramp, along with that "uh-oh" sensation.  It's 11 days past trigger, 6 days past transfer for me.  I started to test the trigger since 4dp3dt/9dpt (top one), that very day the trigger was still visible, the next day it was stark, so I figured it was completely gone from my system.
