So I've read tht they can give u false positives but false negatives too?? I'm supposed to get af Monday (July 20th) so I guess there's still hope even though it says negative?? Did anybody have this nd then get a bfp? I'm still holding out hope cuz I've got alot of the symptoms but I'm still worried tht we missed it this month again? Anybody have any ideas? (I'll be using a clear blue digital on monday of no af comes or should I wait a few?)
