Clear or white discharge is normal, brown, yellow, chunky, or smelly is bad and you should see a doctor. Also if the discharge is too unbearable and servere then you should also see your doctor
Conpletly normal and nothing to worry about if it is just your normal discharge if if it smells or is like yellow and cottage cheese look alike then you could have thrush . If your further along it could be you losing your mucus plug and that could be a bit chunky
