I am a week late with my menstrual. About two weeks prior I began to get sleepy, frequent urinating, headaches, milky discharge, diarrhea and constipation...nipples were very sensitive. When I lay on my stomach it is uncomfortable. Feels like I cant lay flat. Also prior to menstrual date, 2 wks, I had these sharp pains on my left side for about 2 days. I have endometriosis and each month my periods are very noticeable. And when I cramp my cycle starts within hrs. I am now cramping on the right side and no cycle. All HPTs have bn negative. Last one used was two days ago.
