What do you guys think ?

Hi everyone , so my husband & I had unprotected sex on 11/28 & I was supposed to ovulate 11/30 according to the app , I had also taken a plan b right after . But now I’m suddenly bleeding 12/5 , which I know is normal after plan b but it’s not light bleeding it’s normal period type bleeding . Does anyone have any idea if it’s a normal period or heavier bleeding from plan b ?
