About 6 days ago i started spotting incredibly light, with just barely a pinkish tinge to it for about 3 days. Then nothing for two days, and now today i just began spotting again but with even less of a color than before. I am sexually active, and i havent been having any of my normal -your period is about to start- symptoms. I've always dealt with nausea and headaches, but for the last week and a half or so they've been much worse. I've also been pretty irritable and my whole body is a little achy. My nipples were incredibly sore 6 days ago, but now they are fine. Im just wondering if these are all pretty strong indicators i could be pregnant. I usually begin on the 16-22nd of every month.

I've also been a little sick the last three days.,Could this be the reason behind the abnormal period/spotting?
