Af is due today the 30th.. I have been cramping since the 28th and cramping and lower back pain today. I have taken three tests and have been negative. I keep thinking af is going to arrive because I feel wet down there and when I go to the restroom there's no sign of her. I took a test today and it was negative. Anyone have/had a good outcome.. Could I get a positive in a couple days or longer if I don't start af
