Hello! I am 34 years old and have always had regular cycles. I have one child who just turned 14! Today 01/23! I am married and do have unprotected sex. I had a regular period last month! But this month I was 5 days late, had a brown discharge spotted for a couple of days then the discharge, then I started on the 10th or 11th. I stayed on 4 days. Today I have a darker color Brown discharge! What could this mean? I've been emotional, and having light abdominal cramps, and slight back pain! Doesn't hurt or burn when I pee! Oh and a little constapation!
