Me an my boyfriend had a miscarriage 5-25-15. Or aka a chemical pregnancy . Well I took two clear blue digital advanced weeks they both said positive 1-2 weeks . I stopped bleeding an started to have sex again . I missed my period thinking it was because of that. I tested again with the same test an again I'm 1-2 weeks . Has anyone had false reads from these . I also too a regular non digital one I see a faint line . Help !! Cause I don't want to get my hopes up again. Does anyone else see a faint line ?
