discharge? *picture*

* I am about 7-8 weeks. *So I've had a pretty decent amount of white and clear discharge. And today I've had quite a bit of white. But ever once in a while I'll get a light yellow discharge,but it is not consistent. Is this normal? I don't have any pain or discomfort. Like no uti symptoms at all. I see my doctor tomorrow for my first appointment but some real peoples experiences would make me feel a little better:)
