Question

This May Sound Stupid, But I Bought 2 Tests That Say 99% Accurate The Day Of Missed Period.....

If I Took It 2 Days Before && It Came Out Negative (There Was A Really Faded Line But Disappeared && 1 Line Stayed Dark So I Took It As Negative, The Line Disappeared On Both Test??) Then The Day Before My Missed Period Which Was Yesterday && Came Out Negative.

My Period Is Due 30 Of January && No Signs Of Her Arriving, If I Don't Get It Should I Test In Two Days?
