Morning after pill

Shi

Okay so, I took the morning after pill the next day and about a week later I started spotting (so I assumed I'm good at this point) & it wasn't heavy or period like (I had gotten my period littlerally a week before k took the pill). usually I'm early to get my pd but this time I'm late and I don't know of it's the pill that had something to do with that orrr? help please?!
