Sounds more like bacterial vaginosis which is very common its an over growth of yeast in the vagina. yeast infection rarely smells and it a more white milky color. jus ask doc to check u it could b either one. very easily treated with meds n extra yeast/ discharge is very common in pregnancy..
I had yeast infections with my first pregnancy that were like what you described. Just yellow discharge, more than normal. But sometimes just the labia can itch, sometimes the inside of the vagina itches or burns, sex can be painful, and there's more discharge. Anytime you notice more discharge while pregnant, its good to have your doctor check it out. Its basically just a pap smear. They have to swab the inside of your vagina and look at the discharge under the microscope to diagnose yeast or bacterial vaginosis.
Is it possible I dont have either n my discharge just has color to it?
