see the sleep bit would it effect it? as the night of it I was up most of the night xx

it was 2 Saturdays ago I got a positive then on the Monday an tue both negative.. went to the doctor in Wed his came back negative.. but I'm 6 days late now no sign of aunt flow an few people have mentioned a chemical pregnancy to me.. heads all over the place.. doctor didn't mention misscarriage or anything he seemed quite positive with what all he said and told me it could be just because my hormones are all over the show.. it will be my 3rd baby just got my fingers crossed all is okay xox

Could it be that you had more concentrated urine yesterday? (had less sleep/were more dehydrated)
