Spotting ?

Stephanie

on april 7th, my boyfriend came in me. i took a plan b 1-2 hours later. I got my period april 21st-28th. a little longer than usual since it’s usually 5-6 days but it was 7 but i expected it cause plan b does have side effects. it’s now may 3rd & when i peed, i wiped & saw a tiny patch of blood. my boyfriend & i did have sex before i went to pee tho but i’m worried if this is normal or am i pregnant ? do plan b side effects last this long ?
