Spotting 12 days after colposcopy

Hi girls.

I had a colposcopy biopsy done 12 days ago. AF came 7 days ago and ended on cycle day 5 as per usual. However, yesterday and today (cycle days 6&7) I have had small amounts of brownish pink blood tinged cervical mucous which I usually never have when AF ends. Do you think this is still from the colposcopy/ biopsy? I have read that your periods could be heavier than normal after a colposcopy but not sure about the spotting. Anyone else experience this?
