I'm pregnant and have noticed thick balls of white discharge what is this?

Possible yeast ?: A clumpy (cottage cheese- like), white, non- odorous discharge associated w itching, burning, swelling or redness can be due to yeast infections. When pregnant vaginal discharge is thin, white ; milky. If you have a change in color, texture, odor or amount of vaginal discharge ; problems such as pain, itching burning with urination or sex or redness/swelling then it is best to see your gyn.
