my last regular period was on Feb 3rd for one week and on the 26 of the same month, i spotted for an entire week. It was light one day and a little heavier like a couple of drops. And light as in pink on the toilet paper. My period is always on time. It is now March 10th. I should be getting off my period again and it hasnt even come. Whats going on? Should i be worried? Any suggestions on what i should do?
