I'm am now 23 days late for my period did 3 home and a blood test that came out negitive 14 days after my missed period. I have not changed any habits and I have not taken any birth control or gained any weight for over 7 months and its highly unlikely to be the cause of my missed period. Could I be pregnant if my hcg level from the blood test came back as a 5 which is considered negitive.
