Post partum bleeding.. Normal?

Hi all.. I'm almost 8 weeks pp. Had the usual bleeding which lasted a couple weeks. I then started my period around 5 weeks which itself lasted close to 2 weeks. I've now started bleeding again, not a lot, does this sound normal? I'm only seeing the doc for my pp check up in 2 weeks time so not sure if I need to worry or if this can wait until my appointment? Any advice would be appreciated. Also I'm not breast feeding.. Thanks!
