The 21st will be 10DPO for me and I don't think I can wait any longer to test, so I'm going to join in on this thread and test tomorrow!
Not actively symptom spotting, as my body and lifestyle are completely different than they were a month ago. I went from being very active, working outdoors 8+ hours a day, to now non-weightbearing on the couch nursing a broken leg.
The only thing that was unusual was a big glob of CM in the toilet (warning: TMI) on top of a BM on CD7. CM has otherwise been creamy and not made any appearances without me going looking for it.
I'll be amazed if my body manages to fall pregnant with all it has been through this month, but I know I'm not out til the witch shows, so let the POAS obsession begin!
Good luck to everyone testing tomorrow - I'll be checking back (ahem, stalking) often!
