Is this normal with plan b?

On June 1 I had unprotected sex with my boyfriend. A couple hours later, I took the plan b pill. A few days ago, on june 8, I went to pee and I had clear but slightly bloody discharge. The next day more blood came and it was enough to make me think my period came early, it was only like two weeks away, except it was the same color as when I'm getting off of my period. Instead of being red like normal blood, it looks almost like I mixed dirt and blood. Not to mention it smells pretty bad. I've been bleeding, but not a lot, since the 8. I'm not sure if this is what plan b does or what's up. I'm leaving for the military on Tuesday so I'll be taking a pregnancy test within the next few days, but if there's a chance I'm pregnant then I would like to know beforehand. 
Also: should I log this as my period?
