If all you have now is thick white discharge, but it's not smelly or itchy, then it's not necessarily another yeast infection. It might be normal for you right before your period, or it might be something else. But if you said the doctor looked at you again, while having only this thick white discharge, and she didn't see a problem then I'm sure you're fine. Our mucus changes constantly throughout our cycle and maybe you're just now paying more attention to your mucus since you have these yeast infections...??... The general rule of thumb is that anything clear or white is normal mucus; anything discolored and/or itchy is not normal.
Good luck!
yeah you are right... i think i just been noticing more bacause i got the yeast infection in the past... thanks
