Discharge before period...

Abby

I've NEVER been early for a period. Either I have a period or I don't. When it's that time of the month I can feel it, sounds weird but I can. When I feel it coming I can go to the bathroom and whipe blood. Not brown blood but new blood. Today I felt cramping and went to the bathroom and had a creamy brown discharge, no blood. I start my period in three days. I've never spotted before. Like I've said, either I have my period or I don't. I'm always on time. The spotting worried me. Has anyone ever experienced this? My husband and I have have unprotected sex around my ovulation time and after. I don't think I'm pregnant because I know my body. I'm just unsure.
