strange orange/yellow discharge?

Jenn
Hi ladies, 
6 weeks, one day today. Twice I have wiped and a small amount of an orange/yellow sticky string like discharge has appeared. There is no odor, itching or burning. I have no idea what it can possibly be and will be calling my Dr tomorrow, just wondering if it has happened to anyone else. I also have a picture, wasn't sure if it is too graphic to post, but I can if it helps!!
Thanks!
