I know the only way is to wait and find out. But as I go crazy in the waiting, I'm interested to know your instincts - which do you think it is? Here's the details:
I usually have a 26-29 day cycle, with 10 a day luteal phase. I usually get a day or so of spotting before AF but it warms up to light period flow in about 24 hours.
This month, I started spotting evening of 7dpo. Its been lightly on and off for 48 hours now, only once enough to show on a liner, pale pink when I wipe sometimes and other times nothing there. There was one small red stream yesterday. I'm 9dpo now, so AF due on Sunday.
What do you predict: implantation with a BFP to come in a few days? Or just agonisingly slow build up to AF this month?
