Bleeding/Spotting

Hi ladies! 
I was wondering if anyone has experienced spotting/bleeding during their pregnancy? I'm currently 12 weeks 3 days and for the last 2 days Iv had light spotting of bloody and brownish blood. I haven't been able to get to a doctor! This is pregnancy #2 and I can't ever remember experiencing bleeding with baby #1! I'm slightly freaking out but I did a bit of googling earlier and I'm getting mixed reactions!
