I'm a 28 yr. old woman with 4 children. Im married and have not been using any birth control. My menstrual cycles are normal (28 days). I'm 11 days late on my period, and took an otc pregnancy test 3 days ago and was negative. I'm not under any more stress than normal. I have breast tenderness, then need to pee more often, fatigue, crampy, and am very irritable. I haven't had any weird food cravings but seem to want to eat all the time and cheez-its.
