White discharge?

So on Wednesday night, I had unprotected sex. I know it was a mistake, but I was kind of in my head like "wow. You're doing it. You're having sex for the first time. And he's actually enjoying it" 
I went to the pharmacy and they prescribed me the morning after pill, but early today I went to pee and I saw this like white egg discharge there, which happens sometimes in betweenness my periods. 
I'm really confused on where to put this, but I need help. I've been reading online and basically its saying I'm gonna end up pregnant..
