Discharge is normal. Some women have it some dont. The body will actually change the discharge depending on where you are in your cycle too. It can be a bit thicker during ovulation to help the sperm stay put.You should be concerned if its green, has a foul odour(really foul sometimes it does have a smell which is normal) and or if it is kind of frothy in texture. You really shouldnt be afraid to talk to your mom she knows you best and will probably appreciate you talking to her. Good luck and try not to be to concerned.
