the first day of my last menstrual cycle was dec 15 my husband and I were trying to conceive and had intercourse the end of dec which would have been around ovulation. my jan menstrual shouod have shown up around the 13/14 but did not. I had taken multiple tests which all came back negative. I was having symptoms of what I thought was pregnancy.. constipation, back pain, nausea, moodiness and fatigue. Now 2 weeks past what would have been my period start date I am having harsh cramps and bleeding thick dark red. it kind of looks like the consistency of a discharge. I am becoming worried as I have read this could be a symptom of a miscarriage.
