super long period

Luzaurora

so on the 18th of this month I got birth control. I got the implant and that same day I got my period. its been 10 days since and I'm still on my period... this has never happened to me before. last month I got my period for four days and it was just spotting which also has never happened to me. my period is normally a week. idk if its because of my birth control or because of how light my period was last month. has this happened to anyone before?
