Black Light Blood

Bianca

This is my second "period" after getting off of birth control, I'm really just getting black/grey blood and its soo little I dont really need a bad I can just wipe it off. Should I be worried is this concerning? My cycle is acting normal I guess because <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> could accurately predict my period but this blood flow is so odd.
