so i got my period on saterday and me and my bf had sex on tuesday, he pulled out but was unsure as to wheither or not any cum was reliesed inside me, so because of that i went out and took the mornign after pill, so i believed myself to be safe, afterward i senced some slight lower abdominal pain and thought it as a side effect, but then today i began what i thought to be spotting, but later that night my bf fingered me and his fingures were covered in brown blood. considering its been 5 days since the end of my period and 7 since we had sex, i am unsure as to what this means...am i pregnant or and i getting my period again?

PLEASE HELP! and scared!
answers please!
