The mucus plug, is thick, yellowish, it might be a bit brown with red spec in it, but not white...Not sure if this is just normal discharge or yeast infection, is it thick? Or thin? Do you have alot or just a little, how far along are you?
The white discharge is actually normal during pregnancy. As long as it doesn't make u itch or have a foul odor, ur ok. U could always ask ur doctor to take a look at it if ur still skeptical, but it is normal because I get it like daily and my doctor plus lots of books say its normal.
