So AF is due today....

Anika

AF is due today, usually I am like clockwork when it comes to my period. It always starts when it's supposed to and it hasn't started yet. I ran to the store for a test and when I came home to take the test I got a BFN... Does anyone else have experience with getting a false negative? I haven't been having a period symptoms and I always do have bad cramps and bad acne but right now my skin is clear and no cramps.....
