I am late 20 days now, usually I am quite regular or with a small delay of 3 to 5 days, I have no cramping or minor discharge, the mucus has changed its condition from very quite to pasty, the uterus feels plumed and soft and the mucus has changed a bit to a more clear luquidy condition, I am very tired and at during the first 15 days I had a constant urgency to pee all the time, could I be pregnant?
