Brown spotting for 7 days help!!

Angel
So for about 7 days I have been having this brown spotting, past few days some light not really cramps but a sore feeling in my abdomen and my period is not due till Friday. The spotting usually only happens when I wipe and is not heavy but dark. This has never happened my so and I have been ttc for about 6 months, I have looked online and all I'm finding are ppl saying miscarriage has this happen to anyone else and had a full term healthy pregnancy. Also I think it may be too early to test should I or shouldn't I, I don't want to get my hopes up. I'm just really concerned, any insight or info would be appreciated.
