What Is This? Probably TMI.

I've had it for a few days, but my discharge never looks like this. My mom said she had this when she was pregnant with my oldest sister. I had sex with my bf in the 31st when I was ovulating, but I don't know if I'm pregnant or not. I don't want to take a test until after I miss my period. Help please. (Sorry if it's not blurred. I couldn't figure out how to do that.)
