Bleeding one week after plan B

Li

Hello,

I'm wondering if bleeding ( more like spotting) bright red blood exactly one week after taking plan B is normal. I took the pill within 24 hours after unprotected sex ( i had had sex 2 days after my last period). I don't think I am pregnant ( no pregnancy signs or symptoms) and anyways I think it is too early to test. Not the best time to get pregnant.
