Could you get pregnant just before your period due and then not have one I'm ten days late and keep getting negative tests could it be to early if I only fell pregnant 2 or 3 days before my period was due

It maybe to early to tell, have you tried different brands? And a missed period could be from other things like stress or weight gain or loss. The best thing I could tell you is to try another test or see you heath care provider and ask for a blood test
