Is it possible

Is it possible to be day of your period and it be nowhere to be found I got a negative test yesterday like stark white no question if there was any chance of a line ovulation test is negative again stark white is it at all possible that I'm full of it and if I take a test today it would be positive. Is it possible to see so many negatives that I don't see the line. Probably not right so where TF is my period hoe can't go on vacation until I get those 2 lines. Am I broken? Where is my period if I'm not pregnant it should be here right?
