Pregnancy Tests

Jamie
I am 4 days late for AF. some cramps...mainly at night. No breast tenderness like I usually get the week before until she shows... took 4 tests so far. First one I thought I saw a faint line. so tested next day with FMU. definitely BFP. so wanting to confirm before I told anyone I took another that night (cheaper test this time) ... nothing but an evap. decided to wait a day or 2. took one last night and a few minutes ago....BFN with FRER. I am so upset. DH and I were getting excited. .. he says maybe false negatives because our doctor says false negatives are easier to get than a false positive. I say false positive or CP. no AF yet...and I know it's not over until she shows. Any advice?
