Is it normal to still be spotting on day 11?

I got my period 11 days ago and my periods have been very light recently so they’re only heavy for the first 2-3 days and then I usually spot for a few days. This cycle I’m currently still spotting brown blood on day 11. I had sex yesterday because I didn’t see much brown blood so I figured I was finally done spotting but today I noticed more then I did yesterday. I’m wondering if this could’ve been from sex, from ovulation, or if i’m just still spotting from my period? It could be all 3 i guess, but my main question is, is it normal to still be spotting on day 11?
