Hi, I hv vaginal itching for several months, it occur every month after period, during ovulation period.
First time was on March, with creamy cheese discharge
Second time was on May, with watery discharge with some smell
Third time was August, milky discharge..
I am trying to conceive, does this affect me to get pregnant?

It might. It could be a yeast infection but it could be something different. Talk to your doctor and he should be able to perscribe something. You should not be itchy, that is usually a sign of something wrong.

It could be yeast, it could be trich or any other STD. The vagina is a self cleaning oven, so to speak. There should not be itch or discharge with an odor. You need to be examined by your doctor for a proper diagnosis and treatment.
