period & plan b

Okay so I'm not here for judgement, but here's my story I had drunk sex August 13th, no condom. I hoped for the best because I didn't have money for the plan b, then I ended up being late in my period by a week and had sex, again... but sober, with the love of my life but I'm not ready for marriage or baby besides that point, he didn't use a condom and came. He bought me a plan b but the next day; which is the day I got my period. So I took that pill on my period. Today is my second day on it & it's already brown and a little mucous discharge. Idk what I should do?
