I have been under major stress for 2 months last month more than this month. last month like clock work for 37 yrs my period always comes every 28 days always have diarrhea sore breast heavy period but not abnormal. this month it came on time but ive been spotting for 5 days and I have none of my normal pms symptoms, NOTHING just gas, regular stool some times constipated I get small pangs down there lightly but if I become stressed I bleed slightly more
