Confused

My "period" this month was just spitting. It wasn't "fresh" red spotting it was more like "after period" dark red/brown blood. My breast are sooo swollen and sore and my nipples stay erect. Could I be with child?! Oh also major indigestion, nausea, and the runs. No, I haven't taken a test yet, because I'm scared to. ?
