Hi my Af was due 3/31 I tested the day of and the day after and both were negative. The last two months when my Af was near and due I would have sore nipples to the touch and these weird vaginal cramps that let me know Af were coming (Ive never had either symptom before so they were my new Af symptoms once my Af finally returned which is another story altogether but anyway back to the story) This month I've had those same nipples only not as sore to the touch and those same vaginal cramps only not as much only once in a while. Any idea what's going on????
