I'm in the same boat, ladies... TONS of symptoms, including a weird "double" ovulation where I thought I had it on the 3rd and then on the 8th I had the same symptoms! Since 2dpo (if I count it as the 8th being official ovulation) I've had intermittent cramping, Ive been cold constantly, sore breasts off and on, indigestion, didn't think of the nails thing until I was reading the board by mine are really strong too.... Im due for AF on the 21st or 22nd...I did an HPT yesterday and it was negative... not surprising if I really did O on the 8th, but still disappointing...
