I am 9dpt, we transfered 4 embroyos, 2 x 8-cell, 1 x 7 cell and 1 x 6 cell. I've been testing positive on HPT's since Saturday (7dpt), including early this morning. Now I'm worried - is the test accurate? Did it finally work? And god help us - do we have multiples? My blood test is Saturday - but can't help but wonder if anyone has experiences/thoughts that will help.
