Snot Like Discharge at 6 weeks (gross, i know!! i'm sorry) Is this normal??

I am around 6 weeks. Today when I went to the restroom I noticed a small clump of snot like discharge. It was pale yellow in color and odorless but I have never seen anything like it. This is my first pregnancy and I am so terrified something is going to to wrong. We have been trying for years and I want this baby so badly. My next ob appointment is May 18th and it seems so far away. I am be coming so impatient. 

Help!!
