I POAS today, and it is absolutely positive.
However, I just had a miscarriage not quite 4 weeks ago, so it's possible it's HCG leftover from the last pregnancy. That's not likely so, since I took a couple of tests mid-cycle so that I could compare, and the mid cycle tests were increasingly fainter. However, I'm still paranoid that the last mid-cycle test which was not positive at all, was maybe only because the pee was not concentrated enough, and what if this positive today is just from the leftover hcg but from Crazy concentrated pee.
So...yeah, ttc is maddening.
