Bleeding a lot after taking plan b ?

Je

Hey! Hoping someone has been through a similar experience because I’m a little freaked out right now 😔 late July about a week after my period ended I had unprotected sex with my boyfriend so I ended up getting the plan b pill. I got my period again a week later when I still had 11 days til I was expecting it. Googled it and I guess plan b can bring your period on early depending on when you take it in your cycle. That was last week, and when I had sex with my boyfriend last night (I’ve also had sex a few times during the week with no issue) I started bleeding out of no where! Still have 5 days til original expected period but if my period came early then I should still have 22 days left. I don’t speak til my dr til next week and I’ve just been a wreck. Can anyone tell me what might be happening?? I’ve never had this before.
