Spotting, When Should I be Worried?

bhyde1183

I woke up this morning and was had brown spotting. I'm only 8 weeks and trying not to panic but since I've had 2 miscarriages in the past I can't help but to be a little anxious. I'm not having any pain or cramping and I thought it was interesting because this is when my period would be due if I wasn't pregnant. When should I worry about spotting?

Thanks
