helpp ?

so i took plan b about a month ago and i ended up getting my period late, lasted for a week. it ended yesterday. but today i feel moist but there’s no discharge. i feel like i’m gonna get my period again. i feel kinda off. can this be because of the plan b ??? anyone i’m kinda freaking out. usually after my period i don’t feel like this. i don’t have any symptoms. my boobs don’t hurt at all, i don’t really have any cramps, i’m just freaking out and i think it’s kinda messing with me. idk but can anyone relate to any of this ?
