Thread: dark discharge little bleeding help please!

Up to the past year I've always had an extremely regular cycle. This past year for the first time I've experienced numerous late periods, sometimes up to two or two and a half weeks late. I've also always been a VERY heavy bleeder and typically have dibilitating cramps. But this month one week before I was supposed to start my period I noticed a light brown discharge that typically indicates the first day of my period before I start bleeding full blown. I thought it was odd enough that it was a week early, but then I never started bleeding, and the next day it stopped all together. To make things even wierder, it came back the day after it stopped, and I've continued to have a dark dark brownish kind of reddish sometimes discharge for going on six days now. It's not heavy enough of a flow to even fill a full regular tampon for all day but leaves a little bit of spotting in my undwear if I don't wear one. I've been having really bad lower back pains and occasional heaviness in my lower front abdomen, almost like light cramping, but not quite. Other than starting to notice i'm feeling slightly irritable and tired, I dont' really have anyother symptoms indicating pregnancy, but could this be it, especailly cause I'm not on bc and we only use the 'pull-out' method? I thought it might be implantation bleeding, but from what I've read it's too heavy to be that, i think? I'm so confused this has never happended to me before. I don't know if it could just be due to the stress I've been under, or if its just a light period, or if I'm pregnant (which I plan on taking a test to help determine) but i just wanna know if anyone else has been through this... Please give me some feedback I'm really worried...
