I am asking because last month I was 10 days late (which is extremely rare for me because my periods are like clockwork. On the dot they arrive and on the dot the are done. Every month.) I took 4 tests over the course of those days of different brands and all came back negative. On the 11th day I got my period. 😔 I am 4 days late this month but don't want to get that disappointment again. How long can I wait? Is it ok to wait for a long time before testing? Sorry for posting anon. I just feel like the are dumb questions 😐😐😐
