random bleeding...

Ashley Lynn
I'm 7 weeks 3 days out from having my daughter via emergency c section. I pretty much stopped bleeding at 5 weeks with discharge for the past 2 weeks. It was mostly white or clear, sometimes some yellow mixed in. 
This evening I started having some bleeding after some cramping. I haven't done much today because my daughter has wanted mom all day. I'm exclusively breastfeeding and with my other kids I always got my period 18 months later, sometimes 2yrs postpartum. 
Should I be concerned at all?
