Bfitz, I've gotten super faint positives at 7dpo with two of my pregnancies, which means I had to have implanted at 6dpo, so it's not unheard of!
Absolutely nothing happening with me today aside from a headache. I've been watching my heartrate on my fitbit (since someone on this forum realized that their resting heartrate was much higher on their BFP cycle) but today it dropped lower again, so that was anticlimactic. Also, my cervix is back to being low again. I'm only 4 dpo, and I already feel out this month.
