Late after plan plan B pill

Heather

So I had sex with a guy (02-02-17) and I had him use a condom but he pulled it off and came inside me(2:00am), the next morning I went to walmart and got a plan b and took it around 11:00am. I was suppose to start my period 3 days ago, I’m super tired and I have this weird discharge it seems to change day to day, but it’s either white and creamy kinda yellowish/eggwhiteish....
