6 weeks pregnant and little red spotting

pretty
Hey ladies! I'm 6 weeks and 6 days prego with my 2nd child and I'm nervous! Maybe I'm paying too much attention to this pregnancy but since last couple days I've seen spotting brownish whitish discharge. Last night went to the bathroom and saw little blood on tissue. Not sure what to think of it as there is no pain or any other side effects. Please help!
