Yeast infection maybe?

Ive noticed I have a smell with my discharge lately.. Its a white discharge, but is also yellowish.. I've noticed also when me n my bf have sex and I cum (like that white discharge stuff after an orgasm) my bf says "you creamed" lol that it used to be normal like white water like (not clear, just white) but now instead its like cottage cheese looking and sometimes my vj itches.. Does it sound like a yeast infection? Maybe a UTI?
