White discharge during the 6th week of pregnancy is usually normal and is known as leukorrhea. It is caused by increased blood flow to the vaginal area and helps prevent infections. However, if the discharge has a strong odor, is accompanied by itching or irritation, or is greenish/yellowish in color, it may indicate an infection and you should consult your healthcare provider. To have a healthy pregnancy, make sure to eat a balanced diet, take prenatal vitamins, exercise regularly (with your doctor's approval), get plenty of rest, avoid smoking and alcohol, manage stress levels, and attend regular prenatal check-ups.
