Brown only and short period

Hey guys, long story short. Stopped the pill a few months back, to TTC. On Saturday I started my period which is the first correctly predicted period since I've stopped the pill (I have had my period a few times since stopping, but since the apps could correctly predicted this one I assume they are now regulating).

However, it's has been an extremely light flow, dark brown the whole way and a mere two days later, seems like it's finished. My other periods (after stopping the pill) were normal, five day, red, etc.

Could this still be my period or something else?

Thanks guys.
