AF due to start today I have been nauseous, dizzy and crampy for like 5-6 days now and I have no sign of AF yet today normally my knee hurts from inflammation from a car wreck years ago and I have cramps the day I am going to start but that has not happened and I am usually on time. I have been taking pregnancy tests and have all been clearly negative but does anyone see anything on the one from this AM? I want a baby so bad!!
