Hello! I am 17dpo...my last period was September 30th, 2009. It is now November 2nd and I have no signs of AF. Only tender breast...normally I can tell when AF is coming. Is the absence of those signs a good thing?! I tested today and got a BFN! I have lots of gas, backache...and headache throughout the day off and on. Mood swings are definitely there. Could I have tested too early?!
