What do y’all think?

So I had my period June 17th - June 22nd

Five days later, I took a Plan B because of an incident. A week after taking the plan B I started having a period. Now this isn’t spotting... it’s the heaviness of a period, like I’m filling up pads, even leaking on my sheets.

Is there a possibility I could still end up pregnant/be pregnant?

I’m worried because I know it takes 10 days for a fertilized egg to implant, so if anything did happen, the egg probably hasn’t implanted yet and will implant later.

What do you guys think?
