Period or ‘spotting’

So I thought I ended my period as the bleeding seemed to have stopped, however I’m still clotting. I’ve been clotting this whole period, however I’m still going 10 days later, despite the bleeding stopping a few days ago.

Does this count as my period?

Also, I’ve been taking iron lately, could this be what’s causing me to clot so much? I’ve never had a whole period full of clots like I did during this period. I usually only get a lot here and there, for no more than 2 days.
