A little help?

I took Plan B 10 days ago (first time taking it). I started bleeding today (period is due this weekend, around Fri-Sun, CD30-32). It started out like a brown/pink discharge. (Somehow this isn’t letting me post the picture 😭). But it is heavier now. However, I am one of those girls who googles everything, so I’ve read about implantation bleeding. I’m about 11dpo (if I base it on the app). I also know Plan B can make your period earlier or later, but since it was my first time taking it, I’m still stressing out a bit. Thoughts please? Feel free to slap me virtually if you think I am being ridiculous 🤷🏻‍♀️
