Is this normal or sign of infection?

No smell, very watery/milky but typically my cervical mucus doesn’t have particles in it like this. Me and my boyfriend had sex the other night and after he finished inside of me and pulled out, it burned really bad. I only have one partner so I don’t think it’s an STI or STD unless it came from him though I don’t think he would cheat. I’m paranoid because I don’t know what caused the burning and it was very unusual. Is this a sign of infection? I’ve already been to the doctor to be tested, but I’m still waiting on results. I had a yeast infection two weeks ago, but I was medicated for it and my cervical mucus was normal after. While having the infection my cervical mucus has never looked like this.
