I'm 11dpo today and have been testing each day since I got a faint positive at 8dpo. I'm due for my period in 3 days.
I got the bottom positive this afternoon with no hold at all and I drink a lot of water. I felt quite dizzy all day so I'm not really surprised the line is so dark!
I know when I ovulated, so I've definitely got my dates right. I must've implanted at 6dpo.
Any other Mama's with early, dark BFP's? Were they twins?
