❓STRANGE PERIOD FROM PLAN B..❓

Chloe

a while back I took a plan b and expected my period to be late or my cycle to be messed up, but my period actually came a few days earlier than normal. I'd be relieved but my period is different than usual, the blood is a lot darker, almost brownish, it's really sticky - not runny like normal blood, and I'm not bleeding nearly as much. Is this normal, or am I not on my period..?
