Yellow/white cm?

Amanda
I'm 7w1d and for the past few days have had yellowish/white watery/clumpy cm. No odor and no other signs of an infection. Has anyone else had this and been ok? I've read that it's a normal sign but also read some women have had this before a miscarriage. I am a nervous wreck...my first ultrasound is tomorrow and I'm afraid something is wrong 😕
