Hello, and I hope I can help you today. Vaginal discharge gets heavier during pregnancy, and it normally has a yellow creamy color. It should not have a strong odor or itch. Greenish discharge may indicate either the presence of mucus (which can be normal) or either a bacterial or yeast infection. Yeast infections tend to produce chunky discharge with solid portions and no odor, while with a bacterial infection, odor when urinating or after sex is usually present. The way one could tell the difference is by an examination by your prenatal care provider, who could take a look at our discharge and let you know if it is normal. Your high amniotic fluid will need to be continued to be followed during your pregnancy by ultrasound but it most frequently goes away by itself. You likely will need monthly ultrasounds until it does. I hope I was able to adequately answer your question today and that this information was helpful. Best wishes, Dr. Brown
