It is common for the amount and consistency of vaginal discharge to vary throughout pregnancy. As you approach the end of your pregnancy, it is not unusual for the amount of discharge to decrease. However, if you are concerned about the sudden change or experience any other symptoms such as itching, burning, or an unusual odor, it is important to consult with your healthcare provider. They can evaluate your specific situation and provide guidance based on your individual needs. Remember that every pregnancy is different, so it's always best to seek professional advice when in doubt.
