AF is 9 days late. Took 3 tests about 3 days late. All with faint lines. Could have been evap lines??? Since then have taken 3 other tests all negative. No AF. Called doc but won't see me till I'm 14 or more days late. Went to pregnancy support center and a negative test there also. I feel as if I am going crazy? I have never had anything like this happen to me. Any advice is greatly appreciated.
