Mel - Yeah, a blood test would definately show up at 13dpo, it'll pick up any hcg in you system, apparently as soon as bubs implants it lets off 5miu straight away. Which test did you use? I would think you should get a BFP tomorrow morning at 14dpo. You have the same symptoms as me which suggests some hcg is in your system, I get really dizzy if I stand up too quickly! Do you feel warm and fuzzy too, my skins a bit itchy in the shower?

Katie - That's interesting about Crystal Clear being your weakest, which brand was your strongest? I did use first morning urine but I got up 3 times in the night to pee so it really wasn't that concentrated.

Jen - think I'm going to have to test again 2moro morning (and try not to pee 3 times throughout the night). I have 3 Crystal Clear tests left so I thought I'd test every day til Monday, then if it's getting darker I'll call the dr for a blood test. BTW - I've had creamy CM since about 2dpo, quite a bit over the past couple of days.
