After My Bf Ejaculated In Me, I Took Postinor 2,

After my bf ejaculated in me, I took Postinor 2, Two days after......I've been spotting for days/weeks but its been on and off..but i'm seeing signs of pregnancy as well...and lastnight I started seeing very red blood and a passed out a lump looking like a white Pea is inside...in the late night I went to the bathroom to pee because I was feeling cramps in my back and waist, and I sawva big lump fell out, its like half a chicken breast...Is this normal?
