6dpt and spotting

Well, it's 6 days since my FET, and this afternoon I had some pink spotting.  Not a lot...but I'm very familiar with this pattern.  It was actually time for my estrace and progesterone at that time, and I haven't had any spotting since then (about 8 hours ago).  I do have some bad cramping though.  The one time I actually got a BFP, I had absolutely no bleeding.  And with all of my BFNs, I always start to bleed around this time (though this is a day or so earlier than usual).  So, I'm pretty sure this is coming to an end.  I'm not too surprised, and I never got my hopes up this cycle.  I'm ready to call Denver to schedule my 1 day workup, but I thought I should probably wait for a full flow before I make the call.  For now, I'll just continue my meds...and cramping...and q20 minute checks for bleeding.  ;)
