Hey Sam,
I am in the same boat . . .kinda. I'm 6 weeks tomorrow and started spotting 2 days ago. Mine is, however brownish in color. So, not too sure what to make of it. I've been on three forums for the past 2 days and it seems that spotting is quite normal and should go away. It's ok if it's not heavy and bright red. I'd ask your MD though. I have to wait till tomorrow (Monday) before I can check with mine. Ugh. . .so stressful. Good luck though!! I'm sure it's ok ;o)
