Yeast Infection (Candida) Vagina pain (Labia Minoria)

This happened due to hormonal changes in our body, I do experience itchy vaginal during first pregnancy. But, none of the both above mentioned happened. I just wear loose undies, silk type. Because of our body going through pregnancy, hence whatever that body releases through vaginal discharges tends to be imbalance of pH causing some mummies to have yeast infections, itchy, redness, etc.
