Confused...TMI

Dani

I have been spotting brown off and on for 4 days. My period was due today. I spotted this morning but it has stopped. I have had mild cramps in and off. I am 14 dpo. No other symptoms. I tested yesterday morning and it was clearly negative.

Usually I am flowing the day my period is due and never spot as long as I have before my period is due.

Ideas?
