TMI VAGINAL DISCHARGE

Mansi
So my boyfriend and I had unprotected sex and I've taken a couple of Plan B pills, about a week or two apart. I got into the shower and am having light pink-yellowy discharge that's almost grainy?? It looks like tissue but I'm not sure and it stinks. Honestly looks like my vagina threw up and I'm freaking out. Did I miscarry? It's too early for my period...
