So...if i O'd last week when my OPK was super dark (but not quite "positive"), I'd be about 7-8 dpo right now. I've been a bit crampy with an irritable stomach for a few days (with other symptoms I'm positively over analyzing)...
When I was just in the ladies room, I noticed the teeniest, tiniest amount of blood on the tp....the first 'swipe' was brownish, the second was a bit more bright red, but was so tiny, I really had to look...
AF isn't due until next week...could this be implantation???
