Don’t know what’s going on

I started birth control last week, but had to stop four days in due to the daily migraines it was giving me. I was ovulating in the days following my discontinuance and had sex multiple times. I am now five days away from my next period, but I am spotting and have been for two days. I have never had spotting before, in all my years of mensuration, but I can’t decide if this could be from using the birth control for a couple of days or if it could be implantation bleeding. Does anyone have any insight on this?
