WHAT'S HAPPENING?!!

last week i had sex and he didn't pull out so he went & got me a take action pill. now it's been a week since i took the pill & i'm getting blood & brown discharge (medium/heavy flow) like i'm on my period, i've had this problem for 3 days now but i had my period on the 6th of this month... i read up on it and it's saying it's a sign of early pregnancy. what do you think?
