I'm 10/11 dpo today, leading upto today i've had sore boobs for 6 or so days, felt dizzy, sharp stabbing pains in abdomen.
This morning I ran to the toilet as I felt so nauseous but wasn't sick.
Today I've gone to the loo and absolutely devastated that AF had arrived (4 days early?) but it is very pink and light (just about enough to fill a small panty liner - sorry tmi) and I've got mild cramping.
I never had this with my first pregnancy, could it be implantation??
Thanks (still hopeful 
)
