Still spotting 6 months PP

So I’m 6 months PP and after the constant bleeding afterwards, then going on the mini pill I did the usual spotting mid cycle so I went off after a couple months, but the spotting never stopped i start spotting 2 weeks after my period every month, and it last for a week. I didn’t have this with my first pregnancy. Any idea? I had a pap and it was normal a couple months ago
