I sometimes have a light yellowish discharge n other times it's a white cloudy color. It doesn't itch or smell just a lot of discharge. What could it be?

First you should be checked to verify that there is no infection - some do not cause itching or smell. Other than that, if the discharge happens prior to your period, it means you are ovulating and should you want to become pregnant, then this is the time to do it; on the hygene side, wear panty liners to keep your pants from staining. If the discharge is happening every day, then a check up is definitely in order. Please be up front with the doctor as he/she will ask some 'quering' questions which might seem interferring, but they are necessary to come up with a solution.
