My period is about a week late & i have been having a lot of watery discharge. i was told this was not a symptom of pregnancy.. what else may it be?

Infection ; hormones: Some vaginal discharge can be normal. As you go through the month your hormones cause changes in the discharge. In some cases though discharge can be a sign of infection. Causes incluse yeast, bacterial vaginosis, and stds. There are simple tests that can be done in the office to determine if this is normal or not. Take a pregnancy test since you are late.
