All pregnant women have a white vaginal discharge. The amount of discharge varies from women to women.
Should this discharge become excessive, offensive smelling, greenish yellow in colour or begin to cause irritation, it is likely that there is some sort of infection present.
Try to be open with your LMC/MIdwife or Doctor as they can easily reassure you and suggest a treatment.
The most common vaginal infection contracted by pregnant women is thrush/monilla/candida albicans. Candida albicans is a yeast fungus that normally resides in the gut. When you are balanced and healthy, candida retains its yeast form. But when candida in the gut becomes too acidic it starts to grow and gets out of balance and cause problems.
