Plan b and bleeding

My period ended one week ago today, and I had taken a plan b pill 5 days ago. I know it can cause spotting, but I wasn’t spotting.

Yesterday, it seemed like my discharge was just a little pink like it had a little blood in it, so I assumed it was from the plan b.

Anyway, I had sex last night and woke up to a crime scene in my underwear. I’ve been bleeding all day like a period, but mine just ended a week ago. I thought plan b would delay my period if anything. Not make me have another one so soon.

I guess it might not even be an actual period, but it sure is a lot of blood to just be “spotting.”

Is that normal???
