Postpartum bleeding

I had baby girl 6 days ago and my bleeding is now pretty much just spotting or just when I wipe. This was my 2nd pregnancy. Only difference between both vaginal deliveries was with my first I had an epidural and this one was natural. They told me I should bleed for up to 6 weeks (something I already was anticipating) but I've been pretty much spotting for the past 2 days. I know spotting is still bleeding but I was expecting more on the heavier side not just what seems like a period. Has this happened to anyone else or it is happening to them now?
