okay so I usually get AF on the 21 or the 23 . and from the 25 - 27 I took 5 ept all got very faint lines except for one which was a digital first response test and I got a yes on that one too ! so I went to the emergency room to confirm my pregnancy and I got a negative urine test & negative blood test. so I call my doctor make a appointment and go in the next day and she orders a blood test same thing ... negative ! and my levels were the same . so I go back in a week to retest , what do you guys think ?
