Is this normal or not

So I don’t don’t get a lot of yeast infections. Never have. I do however feel as tho I have a little more discharge than most. Normally clear to egg whiteish and thick no smell. I kind of slept with someone from my past and we used protection but I feel like the condom or the oral sex has my PH off. It’s slight yellow in color and still no smell. I’m so paranoid about STD and wonder could I get one from oral sex. Has anyone experienced a yellow discharge that went away on its own. Is my body just clearing its self out?
