I have tested a couple times around 11 or 12dpo, now I just wait for AF to arrive, have not tested at all the last two cycles. I figure with all the evap lines and chemical pregnancies I have seen on this and another site I visit, I would rather just wait it out. And the few times I did test, that glaringly stark white BFN didn't do anything for my mood. When I was pregnant in March I had not been charting and was surprised when AF was late. It was wonderful to take that HPT and see a bright, right away line. If I get pregnant again I would prefer to see something that I know is a positive than squint and tilt an HPT trying to see something. But that is just me...I certainly understand the desire to test early and have done it before...just not doing it any more.
