vaginal bleeding after cesarean?

I just had my 3rd c-section about 10 days ago. I was told the doctor "cleaned me out well" which is why my bleeding was lighter than I expected initially. I was sent home when my daughter was 3 days old, and the next day was the last day that I bled. I've been wearing panty liners for about a week, but I only had spotting for 2 days after I stopped bleeding. Is that normal? I mean, I bled for 4 days. With my other 2 c-sections I bled for a month, so this is new to me.
