A missed period can be a sign of pregnancy, but it can also be caused by other factors such as stress or hormonal imbalances. It's possible for a pregnancy test to give a false negative result, so it's recommended to redo the test after 10 days of missed period for a more reliable result. If you're experiencing excessive white discharge, it could be a sign of vaginitis, and over-the-counter treatments are available for this. You may consider using a 6-day treatment cream for relief.
