Hii Doc... I Had Taken An I Pill Right On

Hii doc... I had taken an i pill right on my day of ovulation in my last cycle due to unprotected exposure..i took the pill within 24 hrs.... After that i had my periods on my regular date and the bleed stopped on day 5 as usual then it reduced to spotting which reduced gradually but still i am literally on day18 after since my LMP and the spotting is present... it isnt heavy but brownish and no smell... I am very worried as to why is it still going on... Please help...
